Nonna Betta
This neighborhood institution serves all the Roman-Jewish classics. Like most of the starters, the carciofi alla giudia (Jewish-style artichokes) are outstanding, and a perfect meal might also include the carbonara, which incorporates dried beef instead of guanciale, or the semolina gnocchi baked in a terra-cotta ramekin. The restaurant gets extremely busy, so don't expect service to be all that attentive; the food more than makes up for it, though.
