Rübezahl is a nice little shop with not too much a variety of products but you will find everything basic you need as well as i.e. vegan sausages and a good choice of organic cleaning products and candles. Most of the vegetables are from local farmers. The owner is very friendly and helpful.
Because it's a small shop the prices are a bit higher than they would be in - say - an organic supermarket.Pros: local produce, friendly and helpful service
