Hi Mike, Ben and Erik,
I'm about an hour outside Düsseldorf, but I do like a wander round the Altstadt
now and again, ...and yes you're right the beer is better as I'm a big Altbier
fan

...I can highly recommend the Schumacher brewery ...an excellent brew.
If you're having a meet-up sometime I could get the train in to Düsseldorf depending
on my calendar, although the run up to Xmas is pretty busy socially I might be able to make it.
