Le Bon Marche, Paris

The oldest department store in Paris and, some say, the first in the world, Le Bon Marché was designed by Gustav Eiffel (yes, that Eiffel) and opened in 1852. The food department, La grande épicerie de Paris, stocks more than 5,000 local and global products—think French artisanal jams, Spanish ham and Welsh mineral water—for the discerning picnicker.
