The hype was worth a look, but it's not something I would go out of my way for. The premise is you go in and order your donuts to your specification. The selection of toppings and glazes are good - everything from indulgent peanut butter and chocolate to lemon and raspberry. The only thing that I wish they had is different types of donuts besides just regular cake. A chocolate , lemon ,maybe even orange flavor would be worthy of more stars.
The other thing is they are great hot/fresh - but reheating them (even following the directions on the box) just loses some of the magic.
Worth a stop, but not somewhere I would visit regularly.
