This great place has a daily changing lunch menu for only 4.20 Euros. Proceeds help the longterm unemployed and also run into HIV-education. Highly recommendable.
Two cheese and one stinging nettle knödel. Originally there should have also been a beetroot knödel which I didn't order bcause I don't like beetroot. Then I tried it from a friend's plate and it was heaven. Great place with locals only and free schnaps.
