This little markt is right in the 'hood, so i go quite often.
The meat stand (Landhof Standl) has excellent, high-quality meat, and the proprietor is super-nice (he speaks great English, but also works with me on my stumbling through in German).
the Fischhaus is similarly outstanding - everything is absolutely fresh, and the fishmongers always offer to throw in a lemon or some parsley or rosemary for free.
the fruit & vegetable guy has a great selection and his stuff is always very fresh, seems to taste better than fruit I buy elsewhere. However, be warned that inside, his produce is NOT 'self-service' -- and he will be a little cross with you if you squeeze a tomato or try to put your paws all over the onions. this is clearly posted btw -- in German...
Prices -- well, you will pay more to buy your groceries here than if you go to Lidl. but you patronize a local business instead of a giant chain, and you're getting better quality for sure. read more
