Some of my friends recommended me J-Co frozen yogurt and they said that it's so delicious..I never try frozen yogurt before, and the only yogurt I've ever try is Yakult..hehheehe. I like the sour taste of yogurt..and make it more complete with any kind of fresh fruits as toppings. Really yummy!! You must try this yogurt!! Best recommended..!! In case, there is no Sour Sally here, in Surabaya.
