Bernie:

Good to hear that Meuser still exists.
Actually "Speckpfannenkuchen" says it all. They are not sweet. (Speck = Bacon).
And Alt Niederkassel is a nice old "village" with some nice schicki-micki restaurants.

I called a friend in Duesseldorf. He recommends: Zum Schiffchen Brauerei in der ALTSTADT, Hafenstr. 5, Phone 0211-132421. He went there with Americans and they wanted to go again and again and again and .... Remember: Schiffchen in der Altstadt! There is another, very expensive "Schiffchen".

You mentioned already the weather. November can and probably will be very dull, rainy etc. Wish you all the best.
