I'm going to give this a resounding "meh". It's not horrible, but it isn't the best thing I've ever tasted either... I enjoyed the fresh fruit concoctions MUCH more than the chocolate ones. Warning: there is no plain vanilla, if you've got picky kids like mine that like just vanilla. Essentially that would basically be like frozen half and half, the cream base isn't flavored or sweetened I guess. Fun concept for sure! I might go again with just friends when it slows down, so I would only have to pay for one, because $30 for four ice creams and an hour and a half deal from start of line to finished product, is a bit much all around. (Not to mention paying $6 for a cup of half and half and a handful of M&M's is a bit insane.) I can say I went, but this will most likely be my only visit, mostly due to value of product to the price paid.
Edit Review: I've noticed reading comments that the wait times vary. I just wanted to say again to give a sense of idea, that yes it was an hour and a half. I got in line at 8:31 and left at 9:57 with the finished product.
