Yolotti Frozen Yogurt, Tulsa

As delicious as frozen yogurt is, Mike and Patty D'Onofrio knew that its tastiness, in and of itself, wasn't enough to build an entire restaurant chain from. Until they considered self-service—letting customers choose their flavor and customize it with toppings that range from indulgent candy to fresh fruit. This became the cornerstone of Yolotti Frozen Yogurt.

But they didn't stop there; they also opted for more health-conscious recipes, such as kosher yogurt free of gluten, fat, and added sugar, as well as dairy-free sorbet. The Yolotti yogurt is also infused with six live and active cultures that promote digestive health.

People can marvel over their creations in a cafe spilling over with free WiFi and board games such as Risk and Trivial Pursuit—both of which are traditionally used to determine the outcome of presidential debates in the event of a tie.
