Old Metairie Bistro (2700 Metairie Road, Metairie, 836-6972) opened recently, taking over the space previously occupied by the New City Grille. Chef Eric Sibley spent years cooking in Chicago restaurants and most recently worked at Monmouth Plantation in Natchez, Miss. His upscale new American menu at Old Metairie Bistro has plenty of Creole touches. Look for drum meuniere with pureed almonds, braised short ribs with truffle macaroni and cheese, and grilled redfish with fried gnocchi. The restaurant serves lunch Monday through Friday and dinner Monday through Saturday.
