Gelateria Fassi

Gelateria Fassi—also known as the Palazzo del Freddo, or Frozen Palace—is Rome’s oldest gelato establishment. It’s been open since 1880, and has survived wars, pandemics, and Italian bureaucracy. The shop practically doubles as a Fassi family museum, with portraits and newspaper clippings covering the walls. Get a scoop of the zabaione gelato (which is kind of like a frozen eggnog) and the vanilla bourbon topped with teeny-tiny bits of toasted peanuts and cocoa nibs. Their famous persimmon flavor is only available in the fall, so keep a lookout.
