Arguably Rome's best trattoria is in Monteverde. From the fried starters (meatballs, gnocchi) to traditional Roman pastas (carbonara, amatriciana) to classic cucina povera dishes such as oxtail, it's cucina Romana at its finest. The dining room is full every night of the week, so you should make a reservation. Cesare gets a lot of buzz. Believe the hype.
