All hail the “food of Florence.” Nothing is more local than a bursting-with-flavor sandwich made of tripe, topped with spicy sauce or salsa verde (with capers, parsley, lemon, garlic and olive oil). And this quintessential street food is served best at Sergio Pollini’s truck on a busy little corner of Via dei Macci, near the Sant’Ambrogio market. This food is sacred in Florence and for good reason. Locals clamor up at lunchtime, while sitting on the benches of the nearby piazza to gobble up these tasty delights.
