White Castle is an American fast-food hamburger restaurant chain, known for its small, square burgers often referred to as "sliders." Founded in 1921 in Wichita, Kansas, by Billy Ingram and Walter Anderson, White Castle is recognized as one of the first fast-food chains in the United States. The brand emphasizes affordability and consistency, offering a menu that features a variety of sliders, sides, and breakfast items. White Castle has a unique cult following, particularly in the Midwest and East Coast, where its iconic burgers and late-night service have become a staple. The chain has also expanded its offerings to include vegetarian options and frozen products sold in grocery stores. Its distinctive white and blue packaging and "Crave Nation" marketing campaign highlight the brand's focus on satisfying cravings for its signature sliders.
