This family-owned, seafood-focused Mexican spot in Logan Square has multiple locations throughout the city. Look for a variety of ceviches and oysters on the half shell to start, and entrees such as whole grilled fish, seafood platters and "seven seas" soup with shrimp, octopus, fish, clams, oysters and cayo (a kind of avocado). Shrimp empanadas are among the most popular offerings, but if you're nursing a hangover, try one of the seafood cocktails, served hot or cold and loaded with everything from shrimp to octopus (they're said to have curative properties). Spanish tunes are pumped through the dining room, and a full bar offers classic tropical libations such as Mai Tais and Sex on the Beach, as well as Mexican beers and tequila. Expect a crowd on weekends.
