I went to a market at the Bastille, but I'm not sure if it's the same one you're talking about. The one I went to you could directly see from bastille statue. It was the only market I visited in Paris, so I have nothing to compare. But it was quite large. It took at least a hour of browsing to go through it all & then I went back in to buy some things after I had seen everything (well with a trip to the ATM in between!). I thought everything was very well priced. I bought quite a few necklaces for 2.50 euros each and friends I gave them to just love them. I also bought & was given sample sizes of some of the food and drinks. I bought a picnic lunch from there too. I don't know if I happened upon a special event/day or not; but there was quite an African influence - I just assumed it was a special thing, but perhaps not. There were tents at one end set up with different items from all different countries in Africa food and misc. items. I also stopped and watched a band with their drums and other instruments for quite a while. This was on either end of the market. At one end of the market there was also a lot of artsy items. Then in the middle it was just a regular market. All kinds of fruits, vegetables, cheeses, meats, drinks, breads, clothing, accessories, etc, etc. It was definately a highlight of my trip :) (A million times better than Rue Cler that RS recommends that I found severely disappointing).
