The covered fish market on the Quai Fernand Moureaux is the heart of Trouville and one of the best places in Normandy to eat fresh seafood without sitting down in a restaurant. Oysters, langoustines, whelks, crabs, and lobsters are sold from the stalls by the kilo; many vendors will open them on the spot and hand you a tray to eat at the quayside tables.
It runs every day of the year, though the selection is biggest in the morning. Combine a tray of oysters and a glass of Muscadet from one of the seafood bars next door for one of the cheapest good lunches on the Normandy coast.
