This place was pretty cool. I came here with my boyfriend, and we spent about $18 on two regular-sized cups. I love ice cream, particularly rocky road, so I went with a premium base, chocolate ice cream, mini marshmallows, and peanuts. It's fun to watch the workers make your ice cream with the nitrogen vaporizing into huge clouds; a bunch of kids were having a super jolly time watching it, so I think kids might appreciate this place a bit more.
I probably won't be coming back anytime soon because I can't really justify spending $9 on a single cup of ice cream with two mix-in's, but it was a fun experience and the cashier was friendly.
