I've been to Rolled Ice Cream multiple times and tried several of their flavors. Every flavor I've tried (so far) has been good. Even potato chip, an unconventional flavor, is pretty good. You really don't taste the potato chip too much, but you do get a crunch in every bite.
This place is definitely a novelty, but I would say the prices are a little on the expensive side for ice cream. Seating can be found along the wall and is also right next to where the line starts. It gets very cramped. I think that the seating arrangement is slightly awkward and could've been better thought out, but what can ya do!
