Across from the Louvre, this store offers three levels of fancy knickknacks and 250 vendors. It's just the place if you're looking for 30 matching Baccarat crystal champagne flutes from the 1930s, a Sèvres tea service from 1773, or a signed Jean Fouquet gold-and-diamond pin. Too stuffy? No problem. There's always the 1940 Rolex with the aubergine crocodile strap. Prices can be high, but a few reasonable items are hidden here. What's more, the Sunday scene is fabulous, and there's a cafe with a variety of lunch menus beginning around 17€. Pick up a free map and brochure of the premises from the information desk.
