Galeries Lafayette is one of those places that you wander into unawares, leaving hours later a poorer and more humble person. The flagship store at 40 boulevard Haussmann bulges with thousands of designers; a Belle Époque stained-glass dome caps the world's largest perfumery. Don't miss the delectable comestibles department, stocked with the best of everything from herbed goat cheese to Iranian caviar. Just across the street at 35 boulevard Haussmann is Galeries Lafayette Maison, which opened in spring 2004. The massive building is devoted to the home, from the kitchenware in the basement to the bedding on the third floor. The Montparnasse branch is a pale shadow of the boulevard Haussmann behemoths.
