Here's a scenario every celiac traveller in Barcelona has faced: it's Sunday evening, you're hungry, and every restaurant you try is closed. You pull up Google Maps, find a place with a "gluten-free options" tag, walk 15 minutes to get there — and it's dark, shutters down, no sign of life. In Barcelona, Sunday closures are a cultural institution. Most independent restaurants take Sunday off entirely, and many close on Monday too. Chain restaurants stay open, sure — but try explaining celiac disease and cross-contamination protocols to the weekend crew at a generic tourist trap on La Rambla. For celiacs, the Sunday-Monday problem isn't just inconvenient — it's a genuine food safety issue. Fewer open restaurants means fewer choices, which means you're more likely to end up somewhere that doesn't understand your needs. This guide solves that. These 10 restaurants are reliably open on Sundays, Mondays, or both, they all have genuine celiac awareness with proper cross-contamination protocols, and the food is worth eating — not just "open, so it'll do." From Sunday paella to Monday brunch, these are the places that keep celiac Barcelona fed when the rest of the city sleeps.

1. Flax & Kale — Open 7 Days, Flexitarian with a Massive GF Menu

Flax & Kale on Carrer dels Tallers is one of Barcelona's most reliably celiac-friendly restaurants — and it's open every single day, including Sundays and Mondays, from morning until late evening. The menu is flexitarian (mostly plant-based with some fish), and roughly 80% of the dishes are naturally gluten-free or have GF versions. The kitchen has a dedicated allergen protocol, and every dish on the menu is coded with allergen icons — the GF ones are clearly marked. Staff are trained to handle celiac requests, and the kitchen uses separate preparation areas for allergen-sensitive orders.

The GF highlights: green pizza on a cauliflower-and-broccoli crust (topped with goat cheese, pesto, rocket, and pine nuts — the crust is entirely GF and surprisingly crispy), poke bowl with sushi rice, salmon, avocado, edamame, and ponzu (naturally GF, served in a coconut bowl), açaí bowl with GF granola, fresh berries, and coconut flakes (available all day — a lifesaver for Sunday brunch), pad Thai with rice noodles and tempeh (the sauce is tamari-based, not soy — confirmed GF), truffle mushroom risotto (arborio rice, wild mushrooms, truffle oil, Parmigiano — no flour, no shortcuts), and grilled sea bass with quinoa tabulé and tahini dressing. The cocktail and juice menu is extensive and entirely GF. The space is large, bright, and buzzy — one of the few places in central Barcelona where you can walk in on a Sunday at 14:00 without a reservation and still get a table within 20 minutes.

📍 Carrer dels Tallers 74b, Raval · €14–22 · Open daily 09:00–23:30 · ~80% GF menu · Allergen-coded menu · Cauliflower crust pizza · Dedicated allergen protocol · No reservation needed most days · Metro: Universitat (L1/L2)

2. Teresa Carles — Sunday Vegetarian Institution, Fully Celiac-Coded

Teresa Carles has been Barcelona's most famous vegetarian restaurant for over a decade, and it's open every day including Sundays and Mondays. For celiacs, the appeal is simple: the menu is entirely coded with allergen symbols, the kitchen has a dedicated protocol for celiac orders, and the food is genuinely excellent — not "health food," but creative Mediterranean cooking that happens to be meat-free. The restaurant occupies a beautiful space on Carrer de Jovellanos, near Plaça Catalunya, with exposed brick, natural light, and a menu that changes seasonally.

The GF standouts: the legendary hummus plate (five flavours — classic, beetroot, roasted pepper, truffle, and pumpkin — served with crudités and GF crackers, not pita), Buddha bowl with brown rice, roasted sweet potato, avocado, pickled cabbage, and miso-tahini dressing (naturally GF, deeply satisfying), mushroom and truffle croquetas (made with a rice flour béchamel — one of the few places where you can eat croquetas safely as a celiac, and they're exceptional), wild rice and grilled vegetable salad with goat cheese and honey-mustard vinaigrette, carrot cake (made with almond flour — GF and possibly the best carrot cake in Barcelona), and fresh-pressed juices and smoothies. Sunday brunch here is a Barcelona institution — arrive before 11:00 or expect a 30-minute wait. The prix fixe weekday lunch menu (€13.50) is one of the city's best deals, and the celiac version swaps out any gluten items seamlessly.

📍 Carrer de Jovellanos 2, Raval · €12–20 · Open daily 09:00–23:00 · Full allergen coding · GF croquetas (rice flour) · GF carrot cake · Sunday brunch · Near Plaça Catalunya · Metro: Universitat (L1/L2)

3. La Boqueria Market Stalls — Open Monday Through Saturday (Including Many Sundays in Peak Season)

Mercat de la Boqueria on La Rambla is Barcelona's most famous food market — and for celiacs, it's one of the safest places to eat in the city. Why? Because the best stalls serve food that is inherently gluten-free: fresh fruit, grilled seafood, jamón ibérico, cheese, olives, and freshly squeezed juice. No flour, no hidden sauces, no ambiguity. The market is open Monday through Saturday 08:00–20:30, and during peak tourist season (June–September and holiday weeks), some stalls open on Sundays too. For Monday eating — when most restaurants are closed — Boqueria is your best friend.

The celiac-safe stalls: El Quim de la Boqueria (the legendary bar-stool counter inside the market — their fried eggs with baby squid is a naturally GF classic, as is the chickpea stew and the grilled prawns with sea salt — tell them "sóc celíac" and they'll confirm each dish), Bar Pinotxo (another iconic counter — the cigrons amb botifarra, chickpeas with blood sausage, is naturally GF, as are the grilled sardines and the escalivada), the fresh fruit stalls (grab a €3 cup of freshly cut mango, pineapple, and coconut — pure, safe, perfect for a Monday morning), the jamón counters (all Iberian ham is naturally GF — point, buy, eat), and the seafood stalls at the back (raw oysters, grilled langoustines, razor clams — naturally GF, served with lemon and nothing else). Avoid: any stall selling croquetas, empanadas, or fried items in shared oil unless you can confirm the batter and fryer are GF.

📍 La Rambla 91, Raval · €5–20 · Mon–Sat 08:00–20:30 (some stalls open Sun in peak season) · Naturally GF seafood, fruit, jamón · El Quim & Bar Pinotxo counters · Cash and card · Metro: Liceu (L3)

4. Can Culleretes — Barcelona's Oldest Restaurant, Open Sunday Lunch

Can Culleretes has been serving Catalan food since 1786 — it's the oldest restaurant in Barcelona and the second-oldest in Spain. More importantly for your Sunday planning: it's open for Sunday lunch (13:30–16:00), when most of the Gothic Quarter's restaurants are shuttered. The kitchen serves traditional Catalan cuisine that is, by its nature, rich in naturally gluten-free dishes. The staff have been fielding celiac requests for years, and the waiters — some of whom have worked here for decades — know exactly which dishes are safe and which contain hidden flour.

The GF-safe dishes: escudella i carn d'olla (the great Catalan stew — chickpeas, potatoes, cabbage, and various meats simmered for hours; confirm no flour thickener, which is the case here — the broth is thickened by the starch of the chickpeas and potatoes alone), canelons — AVOID these, they're the one iconic dish that's wheat-based, botifarra amb mongetes (grilled Catalan sausage with white beans — the sausage here is traditional recipe, no breadcrumb filler, naturally GF), bacallà a la llauna (salt cod baked in a tin with garlic, paprika, and olive oil — no flour coating, entirely GF), crema catalana (the Catalan crème brûlée — eggs, milk, sugar, lemon zest, cinnamon, cornstarch — naturally GF and absolutely spectacular here), and mel i mató (fresh curd cheese with honey — a traditional Catalan dessert, always GF). The dining room feels like stepping into the 19th century — tiled walls, wooden tables, framed photos of celebrity diners. A Sunday lunch at Can Culleretes is a Barcelona experience, not just a meal.

📍 Carrer d'en Quintana 5, Gothic Quarter · €12–22 · Sun 13:30–16:00 (closed Sun evening & all day Mon) · Tue–Sat 13:30–16:00 & 20:00–22:30 · Catalan classics since 1786 · Naturally GF stews and grills · Crema catalana · Metro: Liceu (L3)

5. Honest Greens — Open 7 Days, Fast-Casual with Rigorous Allergen Labelling

Honest Greens is a health-focused fast-casual chain with multiple locations across Barcelona — and every single one is open 7 days a week, including Sundays and Mondays. For celiacs on a tight Sunday schedule, Honest Greens is the reliable fallback: the menu is displayed on boards with clear allergen icons next to every dish, and the majority of the menu is naturally gluten-free. The concept is simple — build a plate from proteins, grains, vegetables, and dressings, all prepared in an open kitchen where you can see exactly what's going into your food.

The GF options: rotisserie chicken (marinated in herbs and olive oil, roasted on a spit — no flour, no coating, entirely GF), grilled salmon with miso glaze (the glaze is tamari-based, confirmed GF), sweet potato and quinoa bowl with tahini, avocado, and pickled onions, roasted cauliflower with harissa and yoghurt, Caesar salad (skip the croutons, the dressing is GF here), brown rice as a base (always available, always safe), and homemade lemonade and kombuchas. The dessert case usually has a GF brownie (made with almond flour and dark chocolate — rich and fudgy). Multiple locations: Passeig de Gràcia (most central), Enric Granados (Eixample), Diagonal (uptown), and Glòries (Poblenou area). The Passeig de Gràcia location is particularly useful for Sunday tourists — it's on Barcelona's main boulevard, steps from Gaudí's Casa Batlló.

📍 Multiple locations (Passeig de Gràcia 82, Enric Granados, Diagonal, Glòries) · €10–16 · Open daily 12:00–23:00 · Full allergen labelling · ~70% naturally GF · Rotisserie chicken · GF brownie · No reservations needed · Metro: Passeig de Gràcia (L2/L3/L4)

6. La Mar Salada — Sunday Seafood and Rice in Barceloneta

La Mar Salada sits on Passeig de Joan de Borbó in Barceloneta — Barcelona's beachfront neighbourhood — and it's open for both lunch and dinner on Sundays. While the tourist-trap restaurants along this strip are generally awful (overpriced paella with frozen seafood and zero celiac awareness), La Mar Salada is the local exception: a genuinely good seafood restaurant with a kitchen that understands celiac disease. The rice dishes are the star, and rice is Barcelona's greatest gift to celiac diners — naturally GF, cooked in homemade stock, and served in the pan.

The GF highlights: arroz negro (black rice with squid ink, fresh squid, and prawns — the ink is natural, the stock is flour-free, the aioli on the side is egg-and-oil only), paella marinera (seafood paella with mussels, clams, prawns, and monkfish — no sausage, no hidden flour, cooked in a wide pan over open flame), fideuà — ask if they offer a GF noodle version; when available, it's made with rice noodles and is celiac-safe, grilled octopus with paprika and olive oil (a Galician classic, naturally GF, served on a wooden board), razor clams a la plancha (fresh razor clams grilled with garlic, parsley, and lemon — nothing else), and crema catalana for dessert. Sunday lunch here with a view of the marina, a plate of black rice, and a cold glass of Albariño is one of Barcelona's great pleasures. Book ahead — Sunday lunch in Barceloneta fills up by 13:30.

📍 Passeig de Joan de Borbó 58, Barceloneta · €16–28 · Open Sun–Thu 13:00–16:00 & 20:00–23:00, Fri–Sat until 23:30 · Seafood and rice · Naturally GF paella and arroz negro · Flour-free stock · Marina views · Reserve for Sunday · Metro: Barceloneta (L4)

7. Federal Café — Monday Brunch Lifesaver in Sant Antoni

Federal Café in Sant Antoni is an Australian-style café that's become one of Barcelona's brunch institutions — and it's open on Mondays when the neighbourhood's other restaurants are dark. The café serves breakfast and brunch all day, the menu has clear allergen labelling, and the kitchen handles GF requests with practiced ease. For celiacs stranded on a Monday morning with nowhere to eat, Federal is the answer: good coffee, proper food, and staff who know what "celiac" means without you having to explain.

The GF brunch menu: eggs Benedict on GF toast (poached eggs, hollandaise made without flour — they use a butter-and-egg-yolk reduction — on Schär GF bread, properly toasted), avocado smash on GF toast with poached eggs, chilli flakes, and lime, açaí bowl with GF granola, banana, berries, and coconut, shakshuka (eggs baked in spiced tomato sauce with feta — served in the pan, naturally GF), corn fritters with smoked salmon, avocado, and sour cream (the fritters are made with cornmeal, no wheat flour — confirm when ordering), and the Federal burger on a GF bun (when available — they source GF buns from a local bakery). The coffee is serious — single-origin, properly extracted — and the fresh juices are all naturally GF. The Sant Antoni location puts you near the stunning Mercat de Sant Antoni (open Monday for the famous book and vintage market) and walking distance to the restaurants in our Sant Antoni guide.

📍 Carrer del Parlament 39, Sant Antoni · €10–18 · Mon–Fri 08:00–23:00, Sat–Sun 09:00–23:00 · Open Mondays · GF brunch all day · Allergen-labelled menu · Great coffee · Near Mercat de Sant Antoni · Metro: Sant Antoni (L2)

8. Elsa y Fred — Open Sunday and Monday in El Born

Elsa y Fred on Carrer del Rec Comtal in El Born is one of those rare Barcelona restaurants that's open seven days a week — Sundays and Mondays included. The vibe is relaxed bistro: exposed stone walls, mismatched furniture, candles on every table, and a menu that mixes Mediterranean comfort food with modern touches. The kitchen has clear celiac protocols, and the waitstaff are trained to walk you through the GF options without making it feel like a medical consultation. For celiacs exploring El Born on a Sunday or Monday, this is your home base.

The GF dishes: tataki de atún (seared tuna with sesame, soy — confirm tamari instead of soy sauce for GF, which they accommodate), burrata with roasted peppers, cherry tomatoes, and basil oil (naturally GF, rich and creamy), risotto of the day (changes weekly — mushroom, asparagus, or seafood depending on season; always made with arborio rice and no flour), grilled entrecôte with patatas bravas (the bravas sauce here is tomato-based, no flour thickener — the potatoes are fried in a dedicated fryer), grilled vegetables with romesco sauce (romesco is made with almonds, roasted peppers, tomato, and olive oil — naturally GF and one of Catalonia's great sauces), and chocolate fondant (made with dark chocolate and almond flour — a rich, GF-safe dessert that rivals any in the neighbourhood). The terrace on Carrer del Rec Comtal is one of El Born's most pleasant spots for a lazy Sunday lunch. Pair with a walk through the El Born neighbourhood and the nearby Picasso Museum.

📍 Carrer del Rec Comtal 11, El Born · €14–24 · Open daily 10:00–01:00 · Open Sundays & Mondays · Celiac-trained staff · GF risotto · GF chocolate fondant · Terrace seating · Metro: Arc de Triomf (L1) / Urquinaona (L1/L4)

9. Cervecería Catalana — Sunday Tapas on Carrer de Mallorca

Cervecería Catalana is one of Barcelona's most popular tapas bars — the kind of place where locals and tourists queue side by side for a table, and for good reason. It's open every day including Sundays, serves tapas from morning until late, and has enough naturally gluten-free options to keep any celiac happy. The restaurant sits on Carrer de Mallorca in the heart of Eixample, and the Sunday afternoon scene — families, couples, groups of friends all sharing plates of jamón, croquetas, and tortilla — is quintessentially Barcelona.

The GF-safe tapas: jamón ibérico de bellota (acorn-fed Iberian ham, hand-carved — always GF, always spectacular), tortilla española (the classic Spanish potato omelette — eggs, potatoes, onion, olive oil, no flour, served warm and slightly runny in the centre), pulpo a la gallega (Galician-style octopus with paprika, olive oil, and sea salt on a wooden board — naturally GF), patatas bravas (fried potatoes with spicy tomato sauce and aioli — confirm the bravas sauce is flour-free, which it is here), gambas al ajillo (prawns sizzling in garlic and olive oil in a clay dish — one of Spain's greatest GF tapas), pimientos de padrón (blistered green peppers with coarse salt — always GF), manchego cheese with quince paste (membrillo — naturally GF), and grilled cuttlefish. The only items to avoid: croquetas (wheat flour béchamel), bread (arrives automatically — wave it away), and anything battered (calamari, etc.). Order a vermouth or a cold caña (draft beer — NOT GF, opt for wine or cider instead) and settle in. Sunday at Cervecería Catalana is Barcelona tapas culture at its best.

📍 Carrer de Mallorca 236, Eixample · €15–25 · Open daily 08:00–01:30 · Open Sundays · Extensive naturally GF tapas · Jamón ibérico · Tortilla española · No reservations (expect a short wait) · Metro: Passeig de Gràcia (L2/L3/L4)

10. Brunch & Cake — Monday Breakfast Rescue Across Barcelona

Brunch & Cake is a Barcelona-born chain with several locations across the city, and every single one is open on Mondays — making it one of the most reliable Monday breakfast and brunch options for celiacs. The menu is Instagram-famous for its towering pancake stacks and elaborate brunch plates, and the good news for celiacs is that GF versions of almost every dish are available. The kitchen keeps GF pancake batter, GF bread, and GF flour on hand as standard, and the allergen menu is detailed and up to date.

The GF highlights: Red Velvet pancakes (a stack of GF red velvet pancakes with cream cheese frosting, fresh berries, and edible flowers — the GF version uses a rice-and-tapioca flour blend and is nearly indistinguishable from the regular), Eggs Royale on GF bread (smoked salmon, poached eggs, hollandaise — the hollandaise is flour-free), avocado toast on GF sourdough (with poached eggs, cherry tomatoes, and microgreens), açaí bowl (with GF granola, fresh fruit, coconut, and honey), shakshuka (baked eggs in spiced tomato sauce with feta and herbs — naturally GF), and fresh smoothies and cold-pressed juices. The best locations for celiac visitors: Carrer d'Enric Granados (central Eixample, beautiful tree-lined street), Passeig de Joan de Borbó (Barceloneta, near the beach), and Carrer de Pau Claris (near Plaça Catalunya). Monday morning in Barcelona doesn't have to mean sad hotel toast — walk into any Brunch & Cake and eat a GF pancake stack with a view.

📍 Multiple locations (Enric Granados, Barceloneta, Pau Claris) · €12–20 · Open daily 09:00–17:00 (hours vary by location) · Open Mondays · GF pancakes, bread, and flour standard · Detailed allergen menu · No reservations (expect queues on weekends) · Metro: varies by location

Your Sunday & Monday Survival Strategy

Knowing which restaurants are open is only half the battle. Here's how to plan your Sunday and Monday eating as a celiac in Barcelona:

• Sunday lunch is easier than Sunday dinner: More restaurants open for Sunday lunch (13:00–16:00) than Sunday dinner. If you're eating out on a Sunday, make lunch your main meal and keep dinner simple — hotel room snacks, a visit to a supermarket, or one of the all-day spots like Flax & Kale or Honest Greens.
• Monday is the hardest day: Monday is the traditional closing day for independent restaurants in Barcelona. Your best bets are brunch spots (Federal, Brunch & Cake), market stalls (Boqueria), and chains with daily schedules (Honest Greens, Flax & Kale). Plan Monday meals in advance — don't assume you'll "find something."
• Stock up on Saturday: Visit a gluten-free supermarket or GF bakery on Saturday to stock your hotel room with GF bread, snacks, and fruit. Having backup food for Sunday evening and Monday morning removes the stress entirely.
• Holiday weekends are double trouble: Spanish public holidays (there are many) can extend the closure period. During puentes (long weekends), some restaurants close from Sunday through Tuesday. The 10 restaurants in this guide are reliable even during holiday periods — but always check Google Maps for real-time opening status.
• Hotel breakfast matters more on these days: If your hotel has a celiac-safe breakfast (see our hotel guide), take full advantage of it on Sundays and Mondays. A proper hotel breakfast buys you time and reduces the pressure to find an open lunch spot immediately.
• Self-catering apartments are the ultimate Sunday-Monday hack: If you're staying in an apartment with a kitchen, Sundays and Mondays become non-issues. Cook breakfast and dinner at home, eat lunch out at one of the open restaurants on this list, and save your restaurant-heavy days for Tuesday through Saturday when the full city is open.
• Use our map for real-time options: Check the interactive map of gluten-free restaurants in Barcelona — filter by neighbourhood and cross-reference with live Google Maps data for current opening hours.

Quick Reference: Sunday & Monday Opening Hours

• Open BOTH Sunday and Monday: Flax & Kale, Teresa Carles, Honest Greens, Elsa y Fred, Cervecería Catalana, Brunch & Cake
• Open Sunday only (closed Monday): Can Culleretes (lunch only), La Mar Salada
• Open Monday only (closed Sunday): La Boqueria market stalls, Federal Café
• Always verify: Opening hours can change seasonally and during holidays. Check the restaurant's Google Maps listing or Instagram page on the day — most Barcelona restaurants post real-time updates on Instagram stories when they close unexpectedly.

Don't Let a Closed Sign Ruin Your Barcelona Trip

The Sunday-Monday closure culture in Barcelona isn't going to change — it's deeply rooted in Spanish and Catalan work-life balance, and frankly, it's one of the things that makes the city liveable for the people who run these restaurants. But as a celiac traveller, you can't afford to wing it on these days. The 10 restaurants in this guide guarantee that you'll eat safely and well every day of the week — no compromises, no sad emergency meals, no risky last-resort choices. Bookmark this page, plan your Sunday and Monday meals in advance, stock your hotel room with backup snacks, and spend the rest of your energy on what Barcelona does best: extraordinary food, stunning architecture, and a culture that — on the other five days of the week — offers some of the best celiac dining in all of Europe.
