Your favorite bio shops (Brussels)

Hello,
I have decided to adopt a more healthy regime and I am looking for bio shops with good prices. There is a nice shop in Place Jourdan but I would like to try others and I am curious what's your experience with bio places. Is any of you part of that circuit where you buy vegetables and fruits directly from local producers?
Please share your experience/tips with me :)
Thx,
EMilia
