Otaleg (which, yes, is gelato spelled backwards) was founded by an employee of one of Rome’s first gourmet gelato-makers. It’s located in between two of Trastevere’s main piazzas, which we recommend hitting once you have your cup or cone in hand. Try the pistachio paired with a scoop of rich dark chocolate, or their silky stracciatella. Also good to know: the fruit flavors change with the season, and are dairy-free.
