"Bancomat e carte di credito- NO!". Several signs on the walls remind you to take "real" money with you. This trattoria is one of the oldest in Rome, as it's there since early 20th century. The place and service is very simple and genuine, very "Roman", I would say. If you want to taste real roman cuisine and just look for simple food, then have a go. You won't be disappointed.
Favorite Dish: "Pasta alla nasona" (rigatoni pasta with a sauce made of tomato and cheese) is their special dish. It looks and tastes like your nonna's pasta. Cool! You can also find all typical Roman dishes such as bucatini all'amatriciana,spaghetti alla carbonara, penne all'arrabbiata, carciofi alla romana. And believe me, they're all very tasty. Worth a visit, definitely.
