Nearly everyone who comes to Paris goes to Versailles, but unless you live here (or nearby) Les Halles, or the markets of Versailles, just a few blocks from the Chateau, are a hidden treasure. First I went to see the organic (bio) markets by the church St. Louis, but the market was tiny, with literally less than ten stands in front of the church.
Les Halles the big market, is open from Tuesday through Saturday from 7am- 7:30pm and on Sunday from 7am-2pm, the covered square and open center square attract locals more than tourists. With easy parking underneath the square, many bus stops within a block or two, and an easy walk four blocks from the chateau, make this a worthwhile stop if you are going to Versailles.
The permanent stands are all in the covered buildings surrounding the open area and feature several cheese shops,
vegetable and fruits vendors,
all kinds of poultry, raw and cooked,
seafood and fish stands,
prepared foods if you don't want to cook,
prepared skewers for your BBQ,
prepared roasts for your oven,
and mountains of shellfish.
If you want dessert, there is of course sweets and patisseries galore.
All around the outside of the covered stands are cute cafés with outdoor terraces if you want to be served your meal and just window shop the vendors :)
