At this traditional Roman restaurant, the premises almost outshine the food. The restaurant’s built over the ruins of the 1st-century b.c Theatre of Pompey (close to where Julius Caesar was infamously murdered), and its various dining rooms and spaces are decked out with charming historical decor, from Roman-style benches and carved capitals to Belle Epoque paintings and furnishings (the restaurant opened in 1922). As for the menu, go for classic Roman fare such as abbacchio al forno con patate (baked lamb with potatoes), or the spaghetti alla carbonara.
