"Far from fancy, Gelateria Perchè No, one of the oldest gelato establishments in Florence, is a family-run shop with an ice cream counter dominating the space; "Perchè No" is written in cursive neon lights, which helps passersby identify it from the street. Founded in 1939, back when proper refrigeration was in short supply, Gelateria Perchè No started experimenting with egg-white spumoni and other cool-but-not-cold whipped sweet treats. Today, those creations live on in the form of signature semifreddo offerings." - Bridget Arsenault
