If you're looking for a wide variety of organic and healthy foods, check out Alnatura. While DM…read morecarries a lot of their products, it's still limited, whereas the grocery store has, well, a grocery store full of stuff. It's on a level similar to Bio Company, so naturally things are a bit pricier here, but sometimes you can find products that cost less than elsewhere.
I also like the open floor-plan here. Whereas a lot of stores are small and cramped, they make good use of the space.
