Fauchon remains the most iconic of Parisian food stores. It's expanding globally, but the flagship is still behind the Madeleine church. Established in 1886, it sells renowned pâté, honey, jelly, tea, and private-label champagne. Expats come for hard-to-find foreign foods (U.S. pancake mix, British lemon curd); those with a sweet tooth make a beeline to the pâtisserie for airy, ganache-filled macarons. There's a café for a quick bite. Prices can be eye-popping—marzipan fruit for €95 a pound?
