The Rosciolis have been running this celebrated bakery for three generations since the 1970s, though bread has been made here since at least 1824. Today it’s the home of the finest crusty sourdough in Rome, assorted cakes, and addictive pastries and biscotti, as well as exceptional Roman-style pizza bianca and pizza rossa sold by weight. This is largely a takeout joint, with limited seating—and the wider range of pizza toppings is only available from noon to 2:30pm. Around the corner is the wonderful Roscioli restaurant and salumeria deli at Via dei Giubbonari 21 and, at Via Cairoli 16, Roscioli Caffè, the latest outpost of the family empire, which offers breakfast treats, cappuccini, and palate-pleasing panini.
