For a quick lunch or snack, make a beeline for Antico Forno Roscioli near the Campo de Fiori, one of the best bakeries in Rome, offering delicious pizza rossa and bianca, bread, pastries and a hot lunch counter, where the pasta and vegetables are weighed by the pound.

Pizza bianca means white pizza and is really denuded pizza — like a firm, crispy focaccia gently kissed with oil, herbs and salt.

It isn’t as ancient as its name implies (it opened in 1972 and was completely renovated in 2007) but it’s a local favorite for its pizzas (priced according to slab size) and primi piatti (usually some pasta or gnocchi, tasty potato dumplings). Come armed with patience, it’s always crowded at lunchtime. My favorite for a quick lunch on the go. A second location, the sit-down Roscioli Restaurant, is around the corner at Via dei Giubbonari, 21.
