OK. This is a concept that needs to make it's way everywhere. I understand that to make it work, you're going to need to place them where their is either great foot traffic or where there is a dessert desert.
I think there were twelve different flavors. And no, I wasn't brave enough to try the taro, no matter what friends were telling us. Settled for the root beer and some vanilla. Being a rather uncomplicated sort, I added only bananas (for the potassium) and pineapple. Well, a couple of spoons of the sugarcane pieces for the contrasting mouth feel.
Yogurt was great. They will hand you a stack of tiny paper cups to sample. Peanut butter was very strange. I imagine that covering that with chocolate syrup might have been tasty.
Anyhow, at 39 cents an ounce, it's a cheap, tasty, and somewhat healthy way to end a night.
It is way better to have one of these places a bit of a drive away, otherwise...
