Mare a Viva
This wholesaler specializes in oysters, mollusks, and crustaceans, and offers a tasting room that has become an obligatory stop for seafood aficionados in town. This may look like nothing but a fish market, but diners are dazzled by the quality of the seafood. There are 24 kinds of oysters, all manner of clams (including Galician percebes), local red prawns in several sizes, and a tank of lobsters and crabs as well as fresh seasonal tuna. Choose between having your fish raw, steamed, grilled, or a la gratin, and dine in the simple blue and white conservatory while enjoying a glass or two of local white wine. You can also get a fine fish couscous (one portion is ample for two people).
