The best place in town for authentic pizza romana, Remo is a Testaccio institution, with a prime location on the district’s main piazza. You can sit at wonky tables balanced on the pavement, or in the cavernous interior, overseen by Lazio players in various team photos. The bruschette al pomodoro are the finest in Rome. A park with swings right across the road makes this a great place to eat with kids. You can try booking but they probably won’t accept: get here early if you don’t want to queue.
