Every few weeks, a new roster of 15 flavors fills the self-serve machines inside Yo So Delicious Frozen Yogurt Bar. While the frosty tastes range from butter toffee popcorn to toasted coconut, each spoonful packs plenty of healthy probiotics, as well as live and active cultures. Upon selecting a yogurt base—many of which are non-fat, sugar-free, or dairy-free—patrons can customize their treats by adding any of 40-plus toppings, such as Oreos or fresh fruit. And, besides its namesake dessert, Yo So also sports several other tasty options, including parfaits and create-your-own smoothies.
