Ok, I've never been a big frogurt fan, but we went to the new Orange Leaf this weekend on 71st and Memorial because we have one opening near our house in the next couple of weeks and wanted to check it out.
All I can say is it's really really good. Self serve, dozens of flavors, some quite obscure like Tarro and Kiwi. They also have tons of toppings, but not the same old garbage you find at other frozen yogurt places. They have fresh blueberries, huge raspberries, several other fruits, and nuts that actually taste good (the almonds were toasted).
You can get both low fat and fat free offerings, and since you help yourself, you can basically fill your little bucket with 20 different flavors if you want. The quality of the product is really good, more like a gelato than frogurt.
I liked it.
