During la belle époque, Maxim's bistro was the most glamorous place to be in the capital. The restaurant has lost much of its cachet (though the food is actually excellent), but for art nouveau buffs, the real treasure is the upstairs museum. Opened by Maxim's owner, fashion designer Pierre Cardin, it's filled with some 550 pieces of art nouveau artworks, objets d'art and furniture detailed during 40-minute guided tours (available in English).
