Stoke up here before or after your visit to the Museo Archeologico, a five-minute walk away. This busy eatery close to the metro station in Piazza Dante has a bewildering variety of hot meals, pizzas, vegetable pies, and rolls. As usual in this type of establishment, pay at the cassa before you eat. There's seating in the back.
