I think Creamistry is just another gimicky, ice cream store with mediocre products, absolutely awful service, and no thought to an efficient process flow. While I understand a place will have its hiccups after just opening, the final product wasn't that good - especially the coconut base which was oddly syrupy, unlike other coconut ice creams I've had. The line also moved about the same speed as another location I had been to (and given up in) previously. Overall, it took 25 minutes to get to the register to order and another 15 minutes to make the ice cream.
Overall, it is probably a fun place for kids with time to idle away, but you're better off picking up a pint of fancy ice cream at Whole Foods - at least that way, you won't have to get frustrated by the inefficient process here.
