Barra de Mariscos
Don't be fooled by the white plastic tables and chairs—the seafood at this open-air eatery easily rivals that at fancier places in town. Hunker down with a cold beer and a bowl of sopa de ostión (a spicy oyster stew), then move on to pulpo encebollado (octopus cooked with onions, butter, and garlic) or the house specialty, camarones a la diabla (a spicy concoction of grilled shrimp and chilies). You may be tempted to make a meal of the chips and salsa.
