As stated before, Rungis is absolutely not secretive at all. Every average citizen knows about it. It was initially within Paris (now Chatelet-Les Halles station) and was moved in the suburb to expand. Not only top-chef buy their food there, but the large majority of french restaurant, not only within Paris but from the rest of France.

I wonder about the doubts raised by the article on the future of Rungis. Rungis is almost a religion. I don't see it declining. In fact it has no competitors at his scale.
