Jolly Rolls serves ice cream in a "hibachi" style. They have large cold plates where they mix together some ingredients in front of you and then roll the ice cream off and put it in a bowl. It is an interesting and fun concept and something great for a first date or the kids, but that's about it.
The portions are small, the ice cream is flavorless and low quality, and the entire thing is just a novelty. Because everything is made to order, expect long waits. I'm happy that I went once to see what it was all about, but there is no reason to ever go back.
