I've been there a couple times, and the different flavors were exceptionally good. Being a frozen yogurt enthusiast, I've been around couple different frozen yogurt places and by far, YoFruitty has been the best. Their mango flavor was my favorite!
I don't know what why other people gave the store a bad rating. I just see smiling faces and people more than willing to allow you to browse flavors. Maybe they were just having a bad day.
YoFruitty gets 5 stars in my book. Awesome flavors, friendly service, and just can't be beat with those other competitors.
