Yogurtology, oh how I love thee! This is my favorite fro-yo place in the Valley! I like their flavors better than MoJo, and it's just logistically easier to get to since it's not located at the busy Biltmore mall. They also have a rewards program where when you spend a certain amount, you get $3 off your next order.
I always get the salted caramel and promegranate fro-yo flavors, and top it off with peanuts and rainbow sprinkles. Love it! The staff is always great too. There's a guy who was working in there for a while who was always really helpful. He hasn't been in there the past couple of times I was in, so I don't know if he's still there or not.
