When the proprietors of Kupz Frozen Yogurt & Coffee decided to brew their own cups of joe, they knew not just any beans could make the cut. That’s why they partnered with Willoughby’s Coffee & Tea, whose carefully selected beans flavor Kupz’s house-roasted blends. On the cooler side, Kupz’s staffers serve specially blended flavors of frozen yogurt, as well as 20-ounce smoothies, which each contain more than five servings of real fruits, such as mangos and bananas. Coffee, yogurt, and smoothie feasts unfold inside a cozy storefront equipped with free WiFi and iPads.
