Steaks on the grill make the sound that signals business is humming for this company. Sizzler USA Restaurants operates and franchises more than 175 Sizzler family-style steak houses in about 15 states and Puerto Rico. The eateries serve a variety of steak, chicken, and seafood dishes and feature a buffet-style salad bar that also offers soups, appetizers, and dessert items. Most of Sizzler's outposts can be found in California. More than 25 of the restaurants are company-owned, while the rest are franchised. The Sizzler chain was started by Delmar Johnson in 1957. In mid-2011, a management-led investment group acquired a majority of the company's interests.
