Cream
3251 20th Ave., Stonestown
Ice cream sandwiches steal the show at Cream, from waffle-based to cookie, brownie, mini-sized, gluten-free, and vegan. There are locations in a few states, and in addition to this SF outpost in Stonestown Galleria, there's a standalone shop in the Mission District. Also, note: Cream caters—and what's more awesome than an ice cream sandwich bar?
