The sopa marinera here is the Latin/Caribbean version of that New England stalwart: seafood chowder. Instead of dairy milk, the fish broth is emboldened with coconut milk. Instead of quahogs and cod, the chowder is studded with shrimp, conch, and snapper. It's a wonderful merging of the Northern and Southern hemispheres, which, after all, is Miami at its best. A small bowl, which is plentiful, runs $4.50; a large, which is obscene, $7.50. Both come with tortilla and side. Adelita is open from 7:00 a.m. until midnight.
