this is a really tiny bio store. It is really compact however, so you can find a selection of products. It does not have much fresh fruits and vegetables. In contrast you can find some soy products, soy milk, yogurt etc. as well as some fake meat products. The lady at the cashier is extra kind, and she says she can order particular products.
it is a lifesaver if you live nearby (for instance Ecole Polytechnique), as it is pretty close to the RER line B.Pros: compact, reasonable selection, very kind cashier
Cons: tiny, not much fresh fruits and vegetables
