Most Frenchmen wouldn't recognize the French bread we use for po-boys in New Orleans as their own, though they should have no trouble identifying with the classic baguettes from a new Uptown bakery. Maple Street Patisserie (7638 Maple St., 247-7912) was opened recently by Ziggy Cichowski, former pastry chef at the Windsor Court Hotel, and Patricia Ann Donahue. It offers an impressive range of breads, cakes and pastries. Don't miss the croissants or the baba au rhum cakes.
