Alexi, Erwin and Yvonne at Pfaffen, one of Cologne's famous Brauhäuser or brewery pubs.
Kölsch is the beer unique to these Cologne breweries.
Kölsch "...is a clear beer with a bright yellow hue, and it has a prominent, but not extreme, hoppiness." (Thanks Wikipedia!)

Strange sculptures were part of the design of Pfaffen's tables.
The sculpture's moustache was rather pointy and intimidating.
