Atlantic oysters from the Bassin d'Arcachon, served raw in their shells with a wedge of lemon, brown bread and butter, and a glass of Entre-deux-Mers or Pessac white.
Where to eat it: 3 restaurants across 1 city.
Oyster farming in the Bassin d'Arcachon dates from the second half of the 19th century, when Napoleon III imported Portuguese spat to compensate for declines in the native gravette oyster. Today the Bassin produces around 8,000 tonnes a year, and the cabanes of L'Herbe, Le Canon and Cap Ferret are the producer addresses. Chez Jean-Mi at Marche des Capucins is the urban Bordeaux address.
Common allergens: Shellfish
Tip from the editors. Arcachon natives need only lemon; avoid mignonette unless you have store-bought oysters of unknown freshness.
Chez Jean-Mi at Bordeaux's Marche des Capucins is the cheapest sit-down oyster meal in the city, with half-dozens and a glass of white before noon.
Try: Half-dozen oysters with a glass of Entre-deux-Mers
Tip: Arrive before 11:00 for a stool at the counter; closed Mondays.
