Heard a lot about this place and had the opportunity to try it recently.
I ordered a the S'mores ice cream in a cup. It was ok. Tasted pretty good (I rarely ever think ice cream is bad!) However, I was expecting to be completely wowed by it, and wasn't really. Other than the toppings, it tastes just like vanilla soft serve you can get at McDonalds.
I would have to say that the portion was enormous and I think would be difficult to eat in one sitting, so I ate half and froze the other half to eat later. If it were not for the portion size, I wouldn't think that it was worth the price (About $7 including tax). I actually wish they had smaller sizes to choose from so I could come back and try other flavours and not have to pay as much for it.
