Not too thrilled. We walked by on our way to eat at one of the restaurants and saw how busy it was. Then walking back, decided to give it a go. It took 20 minutes from time of order to time it was in our hands to get it. I ordered the s'mores one. It was basically chocolate or cream with two large marshmallows on top, with a graham cracker, & chocolate drizzle. For $6.50, not worth it, especially for the wait.
The concept is neat. But nothing special.
