TV host, author, and chef Carla Pernambuco introduces Brazilian elements to a multicultural array of recipes at her popular restaurant. The four-cheese polenta and the red-rice risotto with lobster are among the many the well-calibrated dishes served here. All-white brick walls outside and inside lend Carlota a soothing, stylish feel. The clientele, befitting the neighborhood's demographics, tends to be older than elsewhere in town. Save room for the signature dessert, a guava jam soufflé with melted-cheese sauce.
