It's a perfect opportunity to get together in the heart of town, under the halles du Vieux Marché, for a simple, fresh meal, straight from the adjoining fishmonger's, with a few oysters, marbled razor clams and a fish of the moment at the counter. The Tasting Plate at €26.90 includes Saint-Vaast and Veules oysters, Madagascar shrimps, whelks and a glass of Muscadet.
