For a fast munch-on-the-move follow Florentines to this trippaio (mobile tripe stand) for a tripe panino (sandwich). Think cow's stomach chopped up, boiled, sliced, bunged between bread and doused in salsa verde (pea-green sauce of smashed parsley, garlic, capers and anchovies). A bastion of good old-fashioned Florentine tradition, this trippaio is one of the city's busiest.
