I love the concept!
Ambiance: kid and family friendly. Nothing fancy, very casual.
Service: Outstanding customer service. The guy with the green hair was patient and awesome with explaining how they did things.
Food: My boys got cotton candy ice cream one with two sugar cookies and they other in a cone. They both loved the ice cream. I ended up eating the cookies. It was soft and buttery. To me it complimented the ice cream well. The sandwich was a good size.
Overall: It's a neat concept and a great treat. Prices are reasonable. You should definitely give them a try at least once.
