You need a Sprinkles cupcake right now! This shop is cute and compact - you walk in to meet the case of cupcakes right away. And boy, is it hard to choose! I've been to the cupcake ATM right outside the shop more than I've been inside, but staff is always prompt and polite when I have been in. Definitely join the rewards program if you think you might become a regular!
In terms of the actual cupcakes, they're really good. I'm definitely full after just one - they don't skimp on the frosting, either! My favorite right now is the Salty Caramel, but Red Velvet is (of course) another classic flavor. They didn't have anything peanut butter last time I was in, but I always go for anything peanut butter when it's featured!
