Even though there are three different locations in Wicker Park, Gold Coast and Lakeview, Forever Yogurt has expanded even further by selling its fro-yo on wheels. The Forever Yogurt truck regularly cruises the Loop, and customers will eventually be able to track its location through the aid of a GPS system installed on the truck. Flavors rotate often and fans can vote on Twitter and Facebook to select which will be featured on the truck next. Options include Dutch chocolate, Mom's cake batter and red velvet cake, plus toppings such as fresh fruit, marshmallows and chocolate chips. Up to three toppings are included with either an 8-ounce or 12-ounce cup of yogurt. Track the truck by following @ForeverTruck on Twitter.
