One of the rapidly growing frozen yogurt chains in the Pittsburgh region. I've tried almost all the other chains around and this is definitely my favorite. They offer a variety of toppings ranging from butterscotch, brownie bits, fresh fruit and pumpkin streusel. Reasonably priced (I think it might be a few cents extra per ounce compared to competitors) but the variety is worth it.
Oh and the temperature-sensitive color changing spoons- an added bonus!
