T Willy's Frozen Yogurt, Centerville

T-Willy's Yogurt doesn't just want its patrons to savor its decadent, health-conscious treats—it encourages them to tap into their artistic side. The self-serve frozen yogurt joint lets guests mix and match 15 ever-rotating flavors of sweet and tart yogurt or sorbet, then adorn them with toppings, such as caramel, coconut, or chocolate-covered pretzels. The inevitable deliciousness of each creation belies its healthy nature; each 4-ounce serving contains as little as 100 calories, and all of the frozen-yogurt varieties comply with the National Yogurt Association's Live and Active Culture Program and feature high counts of live and active cultures.
