The available entree choices are: three Hot Wings, one piece of Boneless chicken, four Original Recipe Bites, a Chicken Little, and two Chicken Tenders.
The cup has a divider that keeps the wedges separated from the entree.
Each KFC Go Cup goes for $2.49 (and can easily be used to store other foods in your car after initial use).
