This is one of a lot of similar natural product shops in the area just beside Kadikoy fish market.
It's not all that different from the other ones, however they do at least have some tofu, a reasonable selection of organic grains/cereals/chocolate and some interesting versions of Turkish coffee.
Apart from that, they have the usual other stuff like cheese, olive oil etc.Pros: Okay selection of natural products, Lively, interesting area, Can browse without excessive "buyrun"
Cons: Not much veg. specific apart from tofu
