I totally love the concept and the selection of flavors/toppings, but I wish that there was a good way of gauging how much you're going to need to pay before you head up to the register. Also, the frozen yogurt isn't quiiiite as creamy as what you'll find at other cool/trendy shops like Red Mango. Actually, I don't think I've ever had any frozen yogurt that was up to the standards of Red Mango, so I guess that's a lot to ask for.
So an enthusiastic four stars for the selection and flexibility of toppings (finally there's a place that doesn't charge like $2 if you simply want a spoonful of raspberries along with a pinch of chocolate chips). Add some more creaminess and a scale at the toppings bar, and we're up to five.
