Trippaio del Porcellino

When Florentines fancy a fast munch on the move, they flit by a trippaio, a cart on wheels or mobile stand, for a Panini di Lampredotto. The fourth stomach of a cow chopped up, boiled, sliced, seasoned and bunged between bread. A trippai still going strong is the cart on the southwest corner of Mercato Nuovo.
