Run by Kuffler & Bucher there are several of these stands throughout the Frankfurt Airport. We hit the one by Gate B20. For those world travelers with a pile of foreign cash that you might want to unload, this café takes most of the different currencies in the region — Like British Pounds — that one might not expect, for full value. We had 20 minutes before boarding and Had a knockwurst with curry gravy and a bratwurst washed down with Lichnerweitzen Beer. Finished with a Viennese pastry and we were on the plane. The fancy joynt has sandwiches and a full range of selections.
