I love their ice cream -- Mint Chocolate Chip and Coconut Almond Delight are some of my favorites. They're friendly and prompt (well... as prompt as they can be, given the demand and the centralized location), and the shop itself is tiny-but-cute. No public restroom.
This place has amazing homemade candy and nerdy trinkets that are hard to find elsewhere. Best of all is their case of dog cookies. I let my puppy pick one out and he went crazy for it.
