Hypermart USA was a demonstrator project operated by Walmart in the 1980s and 1990s, which attempted to combine groceries and general merchandise under one roof at a substantial discount. The hypermart concept was modeled after earlier efforts from other retailers, notably French retailers such as Auchan and Carrefour, and the Midwestern big retailer Meijer. All stores used a floorplan that exceeded 220,000 square feet (20,000 m2). They featured a mini-mall, food court, arcade, bank, and other kiosk operations. The ones in Kansas City and Topeka featured McDonald's, Subway, and Popeyes Louisiana Kitchen in their food courts.
