Past 6 years in Pittsburgh, this place has always been my favorite. They offer a variety of flavors and toppings. Best part is you can add everything as much as you like. In the end it is the total weight that matters for the final price. I specifically recommend the fruit bubbles (I think that is what they call it....) topping that I recently tried upon my friend's suggestion. It is like bubbles in your bubble tea, but they pop in your mouth and release fruit flavor. I think the ones I tried are mango flavored.
Overall, a great place to hangout with friends and have yogurt with a bunch of your favorite toppings!
