Sort of a "hip" Carvel (if you remember that). With the plethora of sizes and toppings, there are far more than 21 Choices.
What impressed me the most, however, is that even though this is an extremely popular frozen yogurt place, and the crew had to work really fast to keep up with the patrons coming in, they were always courteous and friendly, and even had time to smile.
Oh yes, the product is excellent.
