Forget the Neapolitan debate, Roman pizza is its own creature: cracker-thin and blistered at the table, or sold by the slice from a baker's scale. Around it orbits a whole street-food grammar of supplì, fritti and the trapizzino.
Romans will tell you, without much diplomacy, that Neapolitan pizza is a different food entirely, and they're right. Pizza romana is rolled cracker-thin, baked until the edge is brittle and charred, and eaten with a knife and fork as a casual, almost reflexive dinner. The other great Roman format, pizza al taglio, is a rectangular focaccia-style slab cut to order and weighed on a scale, sold standing up at lunchtime. Neither is trying to be Naples, and understanding that is the start of eating well here.
For the cracker-thin classic, Pizzeria Da Remo in Testaccio is the benchmark: a loud, no-frills room where the queue is locals, the pizza arrives blistered and fast, and the fritti, supplì, baccalà, fiori di zucca, come first as a matter of ritual. Pizzeria Formula 1 in San Lorenzo plays the same game in a studenty key, packed and cheap and exactly right. These rooms are not 'experiences'; they're how Romans eat on a Tuesday, and that is precisely their value.
Pizza al taglio belongs to Gabriele Bonci, whose Pizzarium near the Vatican turned the slice into something close to an art form, long-fermented dough, toppings that change with the season and the market, sold by weight to a permanent scrum on the pavement. His Panificio Bonci doubles down on the bakery side, with bread and slices that explain why he is talked about the way he is. There is no seating worth the name; you eat it on your feet, which is the whole point.
Then there is the supplì, the fried rice croquette, oozing mozzarella, that is to Rome what arancini are to Sicily, and the trapizzino, a modern invention that has become an institution. Trapizzino takes a pocket of pizza-bianca dough and fills it with the slow-cooked classics of the Roman repertoire: pollo alla cacciatora, coda alla vaccinara, polpette. It is the city's traditional cooking reissued as something you can eat walking, and it works. Mordi e Vai, in the Testaccio market, does the equivalent with boiled-meat panini, allesso di scottona that has been simmering since dawn, for a queue that knows exactly what it came for.
The right way to graze through this is on foot and without a reservation: a couple of supplì while you wait for a pizza, a trapizzino as a mid-afternoon stopgap, a paper-wrapped slice eaten standing on a Prati pavement. Roman street food is not a downgrade from the trattoria, it's the same culinary intelligence, served faster and cheaper, and often eaten with more pleasure.
