Steak 'n Shake Operations, Inc. (doing business as Steak 'n Shake) is an American casual restaurant chain concentrated primarily in the Midwestern United States with locations also in the South, Mid-Atlantic and Western United States, Europe, and the Middle East. The company is headquartered in Indianapolis, Indiana, and is a wholly owned subsidiary of Biglari Holdings. As of 2018[update], 628 Steak 'n Shake restaurants were in operation, with 414 of them corporate-owned, and 214 franchised. The company has since attempted to convert to a fully franchised model. Typical restaurant locations have sit-down, drive-thru and front-window service, resulting in a hybrid of fast-food to-go and diner-style sit-down service. Many locations are open 24 hours a day, seven days per week. The menu features primarily burgers and hand-dipped milkshakes; other entrees, side items, and drinks are also available. The corporation's slogan, "Famous for Steakburgers", refers to its most prominent food item, the Steakburger. The "steak" in the restaurant name comes from that menu item. From Wikipedia
