My rating is only based on the self-serve frozen yogurt as that's the only item I've tried off of their menu so far. I was surprised to find they had a variety of sweet and tart flavors - not as much as Yogurtland but definitely a decent selection. The price is 39 cents an ounce - not too shabby since I expected a Summerlin/Tivoli Village markup.
In addition to frozen yogurt, they offer gourmet ice cream, crepes, Belgian waffles and other treats. The frozen yogurt was pretty good. It isn't the best I've ever had and the selection of toppings was sub par. I was sad that they didn't have any mochi. The tart flavors were a little on the icy side but the sweet flavors like red velvet and cake batter were creamy and delicious.
YoScream is in a prime location, right next to the kids playground and main stage where they hold free performances. There is a lot of outdoor seating available.
I would definitely come back to try their other desserts. I saw someone with a crepe and it looked pretty darn tasty!
