I first discovered this market last December with my parents (who were visiting from Australia) as we walked from the Eiffel Tower to the Champs Élysées. This was a case of being in the right place at the right time, since the market is only there on Wednesdays and Saturdays. The Frenchman and I went there on Wednesday to sample the delights of fresh food (something we sadly had missed living - and being surrounded by supermarkets selling less-than-fresh produce - in London) and to get ourselves something yummy for lunch.
A little known fact about France is that they make a damn good roast chicken (or Poulet Rôti). Every market has at least one Chicken Man, as I like to call them, and there are often debates going on as to which Chicken Man or market has the best roast chickens. They usually come with roasted potatoes which have been sitting at the bottom of the rôtisserie soaking up all the chicken juices. We took a couple of chicken pieces (since a whole one would have been too much and we have less than stellar cooking facilities at the moment), a scoopful of potatoes and a couple of pork sausages that looked really good. We also grabbed a demi-baguette (half a baguette) on the way home, which is compulsory when you're having any meal in France. And why wouldn't you? The bread here is super super good.
The market is quite long, although not the longest in Paris by far (we found out today that the longest in Paris is over a kilometer long!) but it has everything you need to make yourself something good. Smile at the man behind the vegetable stand and he might even throw in a free bunch of parsley - score!
