It’s very easy to eat badly on Campo de’Fiori, which makes this authentic spot with ringside seats on the piazza such a pleasant surprise. Romanesca does dependable, old-school Roman fare at fair prices, including a gloriously juicy pollo e peperoni (stewed chicken with peppers) and abbacchio scottadito, lamb chops hot off the grill. Locals snatch up the tables after 9pm, so a reservation is advised.
