Giving this place 2 out of 5 stars simply because the yogurt is actually pretty tasty.
Unfortunately, the service is absolutely terrible. They hire teenage kids who act like they're at school and that it's a chore to be there. As others have said, the service is severely lacking and I know for me, no matter how good the food may be at a place, terrible service can make it a bad experience and not worth going. They also have a very small selection, usually only about 5-6 flavors from when I go.
I would recommend going to just about any other yogurt shop instead of this one. Yogurtini, Yogurtology, Menchi's, etc. are all much better.
