Olga's Kitchen owns and operates a chain of more than 30 casual dining restaurants that specialize in Greek-inspired, pita-wrapped sandwiches. The eateries also serve a variety of other sandwiches, along with soups, salads, and appetizers. Most Olga's locations offer takeout service in addition to dine-in seating. The restaurants are found primarily in Michigan, with some units serving areas in Ohio and Illinois. The chain was started by Olga Loizon in 1970. Vice chairman Michael Jordan bought the business in 1976.
