What type of responsibility center would a Kohls Caf within the department store be considered?

In an effort to increase the number of shoppers coming into its stores and the length of time those shoppers stay, Kohls (KSS) is adding a small caf (Kohls Caf) to each of two of its department stores in the Milwaukee, Wisconsin area. Each caf will sell Caribou Coffee items including lattes, cappuccinos, and other coffee items. Granola bars, chips, cookies, and other grab-and-go snacks will also be available. These cafs are experimental at this point; Kohls has no plans to add the cafs to other stores.
