Even if it’s your tenth time in Rome, you’ll probably still end up at the Trevi Fountain. Weave past the restaurants trying to lure you in for a lackluster lunch and come to this family-run gelateria instead. The selection is small, since everything’s made in the back kitchen. Don’t skip the house specialty: caffe affogato con semifreddo allo zabaglione, a perfect combination of hot coffee and sweet cold eggy cream.
