Monday's post was about Bonn and Wuppertal; today it's the neighbouring cities of Düsseldorf and Cologne. I've been to both before, some years ago, and you can read my incomplete account of their beers at that time here and here. I was keen to revisit some of the places, though I won't be repeating myself on the beers. In fact, how about an Alt-free tour of Düsseldorf, exploring the other option that most Alt houses have available?
