You've heard of peripatetic chefs. There are a lot of them: Avner Samuel and Marc Haines being the primary examples (though the both of them have been pretty stable over the last several months). Yet general managers have this propensity too. Take Steve Occhipinti. He's swum with Fish, hobnobbed with Cobb at Mi Piacci, flung prime flesh at Del Frisco's and Pappas Bros. Steakhouse, and ogled goldfish bowls at Lombardi Mare. Now he's pegged the next entry on his résumé on Texas de Brazil, the Brazilian churrascaria where gauchos wander around with skewers of dripping meat and force you to eat the stuff until your heart becomes a prime source of Caribbean vacations for your cardiologist. Occhipinti has taken over as general manager of the Cedar Springs location, a sibling to the Addison and Fort Worth Texas de Brazils...Rockfish Seafood Grills has just sprung a sixth location in North Richland Hills, which will be commandeered by Barry Bisset, who will assume the roll of chef/partner. The company has also named Debbie Norman Breard (formerly of the Container Store and Blockbuster Video) as director of new store development. In this role, Breard will scout for land and negotiate leases and new store construction as the school of Rockfish breeds like bunnies. Over the next two months, Rockfish will open a pair of additional locations: One in Round Rock, and in January Rockfish will open at Mockingbird Station.
