Allium Restaurant

Allium Restaurant, Mataro: Pearl Verdict

Allium Restaurant sits at Camí Ral de la Mercè, 504 in Mataró, a coastal city in the Barcelona province that punches above its weight for dining given its proximity to the Catalan capital. With virtually no public data on pricing, hours, or accolades, Allium is a venue where the booking decision requires a degree of groundwork on your part — but that also means walk-in competition is likely lower than at comparable spots in Barcelona proper. If you are planning a special occasion meal in Mataró and want somewhere off the tourist circuit, it is worth investigating. If you need certainty on price point or format before committing, look at better-documented alternatives first.

What to Expect

The name Allium — the botanical genus covering garlic, onion, leek, and chive , signals a kitchen with a point of view on ingredient-led cooking. Restaurants that lead with a botanical identity tend to favour seasonal, produce-driven menus rather than technique-forward tasting formats, which makes Allium a reasonable candidate for a relaxed celebratory dinner rather than a multi-hour omakase-style commitment. That said, without confirmed menu data, treat this as informed inference rather than fact.

Mataró itself sits roughly 30 kilometres northeast of Barcelona along the Maresme coast, accessible by R1 commuter train from Passeig de Gràcia in under 45 minutes. For diners based in Barcelona considering a day trip or a coastal evening out, the logistics are direct. For context on what refined Spanish dining looks like at the highest tier elsewhere in the country, Quique Dacosta in Dénia, Arzak in San Sebastián, and Cocina Hermanos Torres in Barcelona set the regional benchmark , Allium is operating in a different tier and a different register, which is not a criticism.

The Drinks Program

Given that no bar program data is available, what can be said with confidence is this: Mataró sits within the DO Alella wine zone, one of Catalonia's smaller appellations known for white wines made from Pansa Blanca (Xarel·lo). Any restaurant in the area with a considered drinks list has access to genuinely local wines that rarely appear on menus outside the region. If the drinks list at Allium reflects its geography, that is a reason to pay attention to what is being poured. Ask about local Alella producers when you arrive , it is the kind of question that separates a good meal from a memorable one in this part of the coast.

Special Occasion Suitability

For a celebration or date dinner in Mataró, Allium's address on Camí Ral de la Mercè puts it away from the busier central streets, which typically means a quieter room. That is an asset for conversation-dependent occasions. Without seat count data, it is impossible to say whether the room is intimate or open, but smaller venues in this postal area of Mataró tend to run 30–60 covers. Book ahead rather than walk in , even for lower-profile venues, weekend evenings in Catalan coastal towns fill faster than the lack of global press would suggest.

Booking

Booking difficulty is rated Easy. No advance reservation system is confirmed in public data, so calling ahead or arriving at the venue directly is the most reliable approach.
