During Libori 2013 we got some coupons for Kochlöffel as they were having some kind of deal - buy 4 burgers for a price of three, or something of that kind. Couple of days after we went there to take advantage of these coupons. Burgers were actually old... just reheated. Completely dry, hard rolls, and dark and shrunken burgers. Just like someone would re-heat them in microwave. I do not recommend this place. Even with coupons.
