What does White Castle do?

White Castle is a family-owned fast-food restaurant chain, recognized as the world's first hamburger chain, founded in 1921 in Wichita, Kansas. Headquartered in Columbus, Ohio, since 1936, it operates around 345-360 locations across 13-14 states, primarily in the Midwest and New York metropolitan area, generating over $800 million in annual revenue. The chain is best known for its iconic Sliders—small, square steamed hamburgers made with fresh beef. White Castle has a rich history of innovation, including the introduction of drive-thru service and a retail division for frozen Sliders available nationwide. The company has maintained a focus on cleanliness and efficiency, grinding fresh beef daily and ensuring high hygiene standards. With a commitment to family ownership, White Castle has successfully navigated industry changes without franchising, setting it apart from many competitors.
