Duesseldorf is one of Germany's most elegant cities. The Koenigs Allee offers splendid shopping and the Alt Stadt (old town) has one of the best night-life areas in the country.
At least it did back in the 60s and 70s when I was going there. Like other German cities, Duesseldorf has experienced a lot of "cultural enrichment" in recent years-especially since Angela Merkel opened the borders and allowed about a million newcomers to enter from such exotic places as Iraq, Syria, Afghanistan, Somalia, and a few other hell holes.
At any rate, if you are looking for a fine dining experience, may I suggest the buffet line in the Schadow Arcade Shopping Center restaurant. You will literally have to fight for that last shrimp morsel
The captions reads, "Fight between family clans in the Schadow Arcade".
As yet we don't know who the "family clans" are, but it's safe to say it isn't the Hatfields and McCoys, or the Steinbachers and Muellers. More likely it's the Sunnis vs the Shia or the Kurds vs the Turks or maybe it had something to do with soccer.
