Fazoli's, based in Lexington, KY, operates restaurants in 32 states, and just over half of its units are run by franchisees, while the remainder are company owned. The chain has closed some stores over the last few years, as it had more than 400 units in 2002, according to its website.

Sun Capital is now positioning Fazoli's for growth, Matthew Garff, a principal at the equity firm, tells GSR. "The general goal is growth," he says. "There is plenty of room for more Fazoli's." More specific plans for expansion will be determined once the new management team has time to assess the chain, Garff says.

Robert Weissmueller, a former McDonald's executive has been put in place as Fazoli's chief executive officer. He replaces the chain's founder Kuni Toyoda.
