About White Castle

White Castle is an American regional hamburger restaurant chain with about 345 locations across 13 states, with its greatest presence in the Midwest and New York metropolitan area. It was founded in 1921, in Wichita, Kansas. White Castle has been generally credited as the world's first fast food hamburger chain. It is known for its small, square hamburgers – commonly referred to as "sliders" – sold at low prices: five cents from their introduction while gradually increasing in price during the 1930s, with promotional coupons in the 1940s, offering five burgers for ten cents. In 2014, Time named the White Castle slider "The Most Influential Burger of All Time". The company's restaurant locations are white buildings decorated with a castle motif.
