More than 70 toppings wait at the end of Froyoworld's self-service frozen yogurt line. Fresh fruit, candy, and syrups—including honey and Nutella sauces—cap off cups filled with any of 12 low-calorie, non-fat flavors. Depending on the day, customers may find choco-loco banana or pina colada, or even seasonal varieties such as pumpkin. Regardless of the flavor, each yogurt comes loaded with natural probiotics, and Froyoworld keeps the nutritional content of each flavor within eye-sight so customers know exactly what they're eating or pouring into the gas tank of their yogurt-powered scooter.
