2001 Best Mexican Restaurant

Casa Romero

A good rule of thumb for determining whether or not a restaurant serves authentic Mexican cuisine is to scan its menu for ceviche, pozole, flan, and café de olla. Casa Romero, tucked into a tiny Back Bay alleyway, has all four, as well as nicely executed traditional main courses such as enchiladas, verde or poblano; chicken mole; and tenderloin of pork marinated in orange and smoked chipotle peppers. The margaritas are tasty; the service is, well, serviceable enough; and the atmosphere, mellow and intimate. Hit Casa Romero during summer and you can dine in its lovely courtyard.
