This shop is really the smallest health food shop I have ever seen. It's a small extra room integrated into a phamacy. The description above points out most things in their stocks of interest for vegans. I got some veggie spreads, olive soap and vegan biscuits (strange mix, I know). Unfortunately, they don't do tofu/seitan/etc or fresh produce but it's a start. This is probably the only place in Rheinsberg to offer a somewhat noteable range of vegan products.
