One of the best things about where we live in Paris is that we are right next door to the Marche des Enfants Rouges.  It's the oldest covered food market in Paris (since 1615).  Not only can you pick up the catch of the day at the fish stand, wine from the wine stand, organic produce at the vegetable stall or a bouquet from the florist...you can also sit down for a meal or get take out from a dozen stands serving pizza, pasta, sushi, couscous or classic french bistro food.  The atmosphere is very lively and friendly and it is the centre of the neighborhood.  By the way, the market gets its name from an orphanage (which closed about 300 years ago!) in which the kids were dressed in red.
