too expensive ordered a quart size ice cream, had a $5.00 coupon, and still paid over $8.00, meaning without the coupon would have spend over $13.00 for a quart, purchase two, but not sure its worth the trip back to redeem the second. you can go to Bruster's down the street, cheaper and taste a lot better.

The staff is always friendly, helps with selections and even on more than one occasion has offered to take a photo of us all together. It is fun for the kid to watch the ice-cream freezing in front of them. It's more than dessert, it's an experience.

So cool. Liquid nitrogen ice cream! I've passed by this place thinking it was just another frozen yogurt place but it's so much more than that. I recommend going of you've never been. The server was extremely knowledgable

The ice cream was very good. BUT I ordered a large and was lucky to get five bits. For 4.99 for a large seemed quite high in price. I thought the cup would be much fuller for that price. Glad I had a coupon.
