Mamma's in the kitchen and the rest of the family greets, serves, and keeps you happy and well fed at this trattoria popular with artists, filmmakers, and actors. It's near Rome's main university in the counterculture San Lorenzo neighborhood, a short cab ride east of Stazione Termini. The menu offers especially good grilled meats and game birds as well as classic home-style cucina. You can dine outside in warm weather.
