"Perfect For: Cheap Eats Under normal circumstances, if you wanted to eat tripe, tongue, braised meat, or simmered artichokes in Rome you would have to head to a trattoria or restaurant for a full-on meal, devoting precious time and money. But at Box #15 in the Mercato di Testaccio, Mordi e Vai offers Rome's offal, meat, and vegetable classics in fast food form. For around €3.00, get a ciabatta filled with the Roman dish of your choice. I never miss the panino con l'allesso (tender brisket)." - chris stang
