CORTE MADERA -- Il Fornaio (America) Corp., which owns the Corner Bakery Cafe and Il Fornaio Restaurants and Bakeries chains, has been acquired by affiliates of Roark Capital Group, an Atlanta-based private equity firm.

Terms of that deal weren't disclosed.

"Mike Hislop and his outstanding teams at Corner Bakery Cafe and Il Fornaio have built two terrific brands with strong points of differentiation and excellent consumer appeal," said Neal Aronson, managing partner of Roark said of the Il Fornaio chairman and chief executive officer. "We are very excited to partner with Mike to help grow the business."

"The partnership with Roark is a perfect fit, providing each brand with unique opportunities," said Mr. Hislop. "Our ability to leverage Roark's strong background and extensive resources within the franchise and restaurant industries allows us to better serve our current Corner Bakery Cafe partners, while accelerating our pursuit of new franchisees."

Il Fornaio employs about 40 at the Corte Madera corporate office and about 70 at the restaurant here in the Corte Madera Town Center.

"Il Fornaio will continue to operate as is, and no changes in either office staffing or restaurant operations are anticipated," said Michael Mindel, senior vice president of marketing, this afternoon. "There will be no consolidation of any other operations."

Il Fornaio started as a baking school and then retail bakery in Italy in the early 1970s. The concept was was brought to the U.S. in 1981 by Williams-Sonoma, which sold it in 1983.
