One of the more prominent members of Barceloneta Cuina, a restaurant organization that aims to promote the seafood gastronomic traditions of the fishermen’s neighborhood, La Mar Salada serves old-fashioned dishes like bombas (potato balls with a bit of blood sausage in the middle) or heavily breaded and deep-fried squid. Both dishes are usually bathed in the garlicky Catalan eggless mayonnaise called “allioli.” But this inventive restaurant is also known for its lobster fritters and a dynamite version of rape suquet, a seafood soup made with monkfish, clams, onions, tomato, saffron, and sweet paprika. Desserts are out of the ordinary and presented with flair.
