Since opening its first shop in 1981, TCBY has mesmerized millions with mountains of creamy frozen yogurt. Drumming up excitement for low-fat treats was a distinct challenge back then, when ice cream ruled the dessert scene and bundt cake helmed the Senate. Today, the franchise shapes the treat's future with innovations such as frozen greek yogurt, which sports more than 8 grams of protein per half-cup serving. More than 25 varieties of yogurt and sorbet rotate through more than 450 stores nationwide, swirling from self-serve machines at the Folsom and Roseville locations. Flavors range from classics such as old-fashioned vanilla to modern marvels such as cake batter and root-beer float. To accommodate dieters and diners with sugar sensitivities, TCBY sweetens five different flavors with calorie-free sucralose. Filled with fruits, candies, and bite-size baked goods, a toppings bar brims with color and texture, like a rainbow made of extra-coarse sandpaper.
