The experience varies depending on who you get. The ice cream is good and freshly made right before your eyes but nothing too special about it. Taste just like any other ice cream. I think you come here more for the novelty of how your ice cream is prepared as it is pretty cool to watch. They do have unique combinations if you are more of the adventurous type.
I would definitely return because it is fun to watch them roll your ice cream. Expect a lengthy wait time especially since summer is right around the corner.
