Cool concept but man is it not worth it. It's one of those places that you only go once for the novelty. The icecream all costs around $10 and it takes forever for them to make the icecream. It's messy to eat and it's ridiculously sweet. It's so sweet that you just don't want to finish it despite dishing out $10 for a single ball of icecream.
Yes, it's cool and it makes an awesome instagram photo but that's it. I rather go to Bang Bang or Sweet Jesus. At least their service is faster.
