The outdoor market along Rue Mouffetard may be the oldest and possibly the steepest in all of Paris. The street began as a Roman road and by the early 14th century a marketplace was already in operation. It's one of the neighborhoods Hemingway describes in "A Moveable Feast." Open for business Tuesday - Saturday, it's busiest for food shopping (and photo ops) before noon. It also has several fine chocolate shops, sidewalk cafés and a couple of notable Greek eateries - Au P'tit Grec for sandwiches, crepes and kabobs and La Crete for more sumptuous meals.
