Dirt-cheap and immensely popular with locals, Montecarlo feels like a big party: Efficient, flirtatious servers sling piping-hot, thin-crusted pies, and the wine and beer flow freely. Sure, they serve other fare, but seriously, come for the pizza. Montecarlo’s longtime rival, the equally recommendable Baffetto, is just around the corner on Via del Governo Vecchio. Lines at both joints are long, but move quickly. Cash only.
