Gio Gelati
$ | Cow Hollow
San Francisco is filled with wonderful ice cream shops, but for the real-deal smooth, airy gelato, this Union Street gelato maker is the address to know. It's all about the ingredients here—pistachios from Sicily, local fruits in season, a sour cherry variety from a particular part of Italy—and the results are delightful whether it's a hot, sunny day or the fog feels as cool as the gelato.
