The food was cold, and on the bill we found an additional 10% raise ("Trinkgeld") which means tip for service. However, in all german restaurants prices are inclusive service. I suppose they thought we were american. In the USA tipping is common. Avoid this place. For a good meal with a fair price try Nolle, Deponie 3 (both Georgenstrasse) or Marktwirt (or so) in Bleibtreustrass. Bon appetit!
