Cars, suits, and wedding rings. With some things in life, customization is key. MoFroYo Frozen Yogurt, which touts a self-serve bar with 21 rotating flavors of frozen yogurt and more than 100 toppings, brings this concept to your taste buds. Its self-serve machines swirl out traditional tastes, such as vanilla, and exotic blends, including cake batter, sweet coconut, and strawberry shortcake. The amounts, toppings, and mouths they?re eaten with are all up to the customers. MoFroYo's flavors change regularly, often with the seasons. For example, during the fall there's pumpkin pie ? la mode and in the winter mouths dance with peppermint stick and white-chocolate mousse.
