Diddy Riese

Even on a chilly afternoon, the line for Diddy Riese can stretch around the block. It's no wonder: At just $2, the massive ice cream sandwiches here are a seriousl steal. Choose any two freshly baked cookies (chocolate chip, oatmeal raisin, peanut butter...you name it), then add a scoop of ice cream, with flavors ranging from vanilla bean to strawberry cheesecake chunk. Just remember: it's cash only.
