Very informal, bustling trattoria in a working class neighborhood of Rome.  There is a menu but, in fact, the waiter recites the daily offerings and you make your choices from these.  Everyone starts with a pasta – large and bountiful – and most of the specials are hearty meat dishes though it’s possible to have a second course of salads and vegetables. The wine list has lots of reasonably priced local wines. It’s a good choice for a large group, and they serve quite late.  The staff is busy but quite friendly and helpful. The food is hearty and bountiful rather than subtle and sophisticated.  Favorites:  Cacio e peppe; pasta Norma (rigatoni with tomato sauce, parmesean cheese and eggplant); roman artichokes; puntarella (local vegetable with anchovy and olive oil sauce); tiramisu
