I've been here a couple of times now, and I have to say, it's my favorite fro-yo shop in Vegas (we can always use more cold refreshing treats). The store is clean and stylish, they have wi-fi available, the staff is really friendly. The yogurt is probably the best I've had - original tart is my new favorite flavor. They have tons of toppings as well, including lots of fresh fruit.
Bonus fact - the foursquare mayor of this place gets a discount! That was a nice surprise when I checked in yesterday :-)
