Testaccio Specialty

For some really great street food, stop here to pick up modernized Roman sandwiches called Trapazzini. Trapizzino is the namesake take-out place that invented them, and there are a growing number of satellite outposts sprinkled throughout the city. The chicken cacciatore is a must; there are a variety of meat and veggie-centric options.

Serious serious Rome street food–at its absolute best. Sergio Esposito, a lively (you want what he's having) former butcher, creates epic, layered, Instagrammable sandwiches that as much an experience as they are a meal. And his approach is a mix of classic and inventive: Choose your favorite historic Roman dish, from buttery, tomato-y homemade meatballs to rich Picchiapò, and watch Sergio complement it between his homemade bread.
