In an industrial atelier (workshop) with bare cement, metal columns and big windows, Soya is a 100% cantine bio (organic eatery) in what was once a staunchly working-class district. All dishes here are vegetarian and many are vegan, such as shiitake and ginger garam masala curry or couscous, quinoa and candied grapes. On weekends, the brunch buffet brims with fresh salads.
