FAO German Fight Fans / Dusseldorfers

[ding-ding]

I am going to be heading over to Dusseldorf for the Wlad vs Mormeck fight.

Any tourist info will be much appreciated. I have visited Dusseldorf for business before so I know the Aldstadt & the Rhine Promenade are good for eating and drinking... Are there any other must see spots / sights in Dusseldorf? I want to make the most of this trip

cheers in advance
