Bernie:
I have read your Duesseldorf info. I think it could not have been written better - perfect job. I have lived in D'dorf half a year, many, many years ago.
I would like to mention 2 venues:
1. There is/was a pancake restaurant in Alt-Niederkassel (Speckpfannenkuchen at Meuser?)
2. Friends tell me the harbor area is mega in?! Hafengegend, lofts, restaurants?
