If Marseille is a city of 111 villages, Cinq-Avenues is a village that feels like a mini-metropolis. From boulangeries to boucheries, the neighborhood brims with personable local businesses rather than impersonal chain stores. Some places have seen generations pass through their doors – like Maison Calambo, a family-run spot that has been shucking shellfish since 1946. Named for a species of gray shrimp found in the Atlantic and the Mediterranean, this small écailler (the French word that is both noun – oyster seller – and verb – to open an oyster) embodies the prized Gallic custom of seafood stands. On Christmas, New Year’s Eve and during other celebrations, French families gather around teeming shellfish platters, the perfect pairing to festive bubbles and the ideal antidote to fatty foie gras.
