Trattoria Da Enzo al 29

A tiny Trastevere trattoria that draws queues down the street for the Roman trinity — cacio e pepe, carbonara, and amatriciana, all made the traditional way. No reservations, no shortcuts, no regrets.

No reservations means the only real strategy is timing: the kitchen opens for lunch at 12:45 and dinner at 19:45, and arriving right at either time is the difference between a short wait and an hour queuing down the street once word gets around. The dining room seats only a few dozen, which is exactly what keeps the kitchen consistent — there's no version of this place that scales up without losing what makes it good.
