Very few restaurants boast the kind of successful split personality found at this Plateau Portuguese establishment. One side is a softly lit dining room for romantics; the other a loud, rambunctious tavern where shouting and cheering is the order of the day. The food, however, is uniformly good, from the restaurant's famous grilled chicken to Carne Alentejana, a typical Portuguese dish of pork and clams. Service is either relaxed or frenzied, depending on your choice of room.
