Gelateria Il Duomo is located on Sorrento's main thoroughfare, just before the Cathedral. Stop here for a coffee, frozen yogurt, or artisan gelato any time of day. Say hello to Alessandra, Carlo's sister, who learned the ice cream art from papà Gerardo and who will be happy to let you taste his special flavours, including walnut and Sorrento citrus. © iStock / mkistryn
