Steak 'n Shake

Steak 'n Shake Operations, Inc. 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, 628 Steak 'n Shake restaurants were in operation; 414 corporate operations and 214 franchised establishments, although the company has since been attempting 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 service and diner-style sit-down service. Many Steak 'n Shake restaurants are open 24 hours a day, seven days per week. The menu features primarily burgers and hand-dipped milkshakes, though other entrees, side items, and drinks are also available.
