You might say this company has a one-two punch for meat and potato lovers. Del Frisco's Restaurant Group operates two upscale steakhouse chains, Del Frisco's Double Eagle Steak House and Sullivan's Steakhouse, with about 25 locations in 15 states. Its more than half dozen Del Frisco's locations offer upscale dining in a contemporary surrounding, while its somewhat less pricey Sullivan's chain features an atmosphere reminiscent of a Chicago-style steakhouse. Both concepts serve premium cuts of beef along with seafood, lamb, and pork dishes, and both offer an extensive wine list. The company is controlled by Dallas-based private equity firm Lone Star Funds.
