Ristorante Arlù
This tiny family-run restaurant has changed a lot since it first opened in 1959 as a simple trattoria. Today you'll still find classic Roman dishes on the menu, but it's worth trying original creations like salmon marinated in Aperol with avocado and savory panna cotta or the homemade ravioli stuffed with ricotta and topped with octopus confit. There is just a handful of tables inside, but in the warmer seasons you can sit outside on the cobblestone street.
