The parent of the Sizzler steak chain...

The parent of the Sizzler steak chain said Robert Holden, the head of its fastest growing subsidiary, Pat & Oscar’s restaurants, would resign effective Sept. 30. Charles Boppell, CEO of the chain’s parent, Worldwide Restaurant Concepts in Sherman Oaks, will take on Holden’s duties until a successor is named.

With sales slowing at the Sizzler brand, Worldwide has been looking to Pat & Oscar’s for growth -- expanding the chain from seven when the company acquired it in 2000 to 21. But Pat & Oscar’s, which offers pizza and ribs, saw its same-store sales fall by 3.4% in the latest quarter.
