Giolitti is a long-standing cafe in Testaccio, Rome, selling gelato, coffee, and desserts. Gelato flavors such as pistachio and zabaione are topped with handmade whipped cream, and customers choose two flavors and order them in a cone or cup. It began in 1890 as a dairy shop and became a supplier to the Italian royal household, now run by a third-generation family. Staff service is cold, and payment and gelato pickup are handled in an assembly-line manner.
