This place offers you a wide range of vegan dishes (there was seitan (wheat gluten), samosas, indian curry and so on when I was there). It was really good but very very expensive when you think that's a self-service restaurant!
I still have the receipt, just to give you an idea:
0,420 kg x 42.OO CHF/kg = 17,60 CHF (around 14 euros...) and I was still hungry...!
Cons: too expensive
