Carbo-load before the opera or between museums with fresh focaccia stuffed with tangy tuna and capers or lean bresaola (air-cured beef), rocket and seasoned Grana Padano cheese. On cold days, get your porchetta (pork) and gorgonzola cheese panini toasted to gooey perfection. Plan your breaks before 1pm or after 3pm to snag a stool indoors (no extra charge).
