Re. Zur Post
I visited Wildenrath three months ago and Zur Post is still there. Externally it looks much the same as it was in '67 - '69, but inside it has gone a bit up-market. More a restaurant with a fancy bar than how Herr und Frau Schiffers ran it forty odd years ago. When I asked for 'ein grosse beir' I was presented with 0,4 litres of Bitburger in a stemmed flute type glass vice 0,5 litres in a German 'sleeve' glass.
Don't even mention 'halb henchen mit fritten!'
