It couldn't be simpler. Serve yourself up a healthy helping of frozen yogurt. The instructions are right there in large black-and-white letters clashing with the overall tropical pastel decor: Select cup size, dispense frozen yogurt, pick favorite toppings, weigh and pay. Flavors range from green apple to "death-by-chocolate" and can be topped with anything from crumbled Heath bars to graham crackers. Mix and match until your taste buds overload. Only yogurt available, no ice cream.
