La Coupole, Biarritz

La Coupole occupies the ground floor of Biarritz's old market hall on Rue Gambetta, a graceful Art Deco building whose copper-green dome has been a landmark of the town center since the 1930s. The restaurant has claimed the most atmospheric space in the building and serves what is arguably Biarritz's finest grand plateau de fruits de mer—a multi-tiered monument of lobster, spider crab, langoustines, Arcachon oysters, whelks, and clams that arrives at the table on a bed of crushed ice and seaweed, accompanied by home-made mayonnaise, shallot vinegar, and rye bread. The kitchen's strength is in the handling of the Atlantic coast's seafood: sea bass roasted with Espelette pepper and olive oil, turbot grilled on the bone, and a bisque that concentrates the ocean into a bowl. The room itself is divided between a brasserie-style main hall under the dome and a more intimate mezzanine level above. White tablecloths, polished brass fixtures, and the gentle sound of the market trade from the floors above give it a timeless brasserie atmosphere—busy and convivial without being loud. The wine list leans towards the Atlantic whites that suit the food: Muscadet, Picpoul de Pinet, and the Basque Txakoli, alongside a considered Bordeaux selection for red drinkers. Service is professional and accustomed to a mix of local regulars, Spanish day-trippers from San Sebastián, and international visitors. Reservations are essential at weekends from June through September.
