I didn't have an opportunity to try a full sized cake but the red velvet bundlett was divine...super moist and not overly sweet. I love the fact that you can buy these mini-sized cakes - they're still shareable and reasonably priced $4 - $5.
Service was friendly and the store is super cute and clean. Since I want to be able to fit into my clothing, I can't stop in too often when visiting Phoenix but I will make it a point to come back to try more flavors.
