This city institution, whose name translates as "oyster bar," has earned a solid reputation for impeccable seafood. Fish and shellfish are delivered twice each day, practically guaranteeing quality. Preparation varies but often encompasses frying, grilling, and the like. A few meat dishes are available for die-hard carnivores. Casual meals are served downstairs amid fish tanks and tilework; upstairs, more elaborate surroundings accommodate those who desire special-occasion dining.
