This restaurant has a long pedigree, open in one form or another since 1870, with seating inside or out on the piazza in the heart of the old Jewish Ghetto. It’s essentially a Roman trattoria, with the welcome addition of a salad/antipasto bar (14 choices) in summer and hot “polenta bar” in the winter. Otherwise stick with the classics: fried artichokes, outstanding pasta alla carbonara, and exceptional fettuccine with pistachio and smoky mozzarella. For dessert, try the homemade sorbets, prepared with fresh, seasonal fruits.
