You might say this company is angling for hungry customers from the pool of seafood fans. Rockfish Seafood Grill operates about 15 rustic-themed seafood restaurants mostly in the Dallas and Houston areas. The small chain's menu offers a wide variety of seafood selections and features specialty appetizers and signature entrees. For meat-eating customers, the restaurants offer beef and chicken options. Randy DeWitt and his wife, Michele opened the first Rockfish location in 1998. CEO Henry Leonard and Dallas restaurant investor Ray Washburne control the company with backing from a group of private equity firms.
