Trastevere is home to some of the best bars and restaurants in Rome. After a few drinks at Bar San Calisto, wander over to Fiordiluna for a scoop or two. The creamy mascarpone might surprise you with bits of chocolate and biscuit, and the pistachio packs a wonderfully nutty crunch. The classic yogurt flavor, meanwhile, could easily put your hometown froyo spot out of business. And if you still need to buy a souvenir for the person watching your dog at home, their homemade jams are easy to slip into your checked bag.
