White Castle (restaurant)

White Castle is an American regional hamburger restaurant chain with 377 locations across 13 states, with its greatest presence in the Midwest and New York metropolitan area.[6] It has been generally credited as the world’s first fast-food hamburger chain, founded on September 13, 1921.[2] It is known for its small, square hamburgers referred to as “sliders”. The burgers were initially priced at five cents until 1929 and remained at 10 cents until 1949.[7] In the 1940s, White Castle periodically ran promotional ads in local newspapers which contained coupons offering five burgers for ten cents, takeout only.[8][9]

Despite being founded in Wichita, Kansas, the restaurant has not operated a location in the city since 1938.[10]

On January 14, 2014, Time labeled the White Castle slider as the most influential burger of all time.[11]
