The Salon has drawn comparisons with the avant-garde "happenings" at the now-defunct Creamcheese club where local artist Joseph Beuys (a man so bonkers he once imprisoned himself in a gallery with a coyote for a week) would hold court doing Handaktion (hand movements) for three hours.
Andy Warhol regularly swooped by Düsseldorf to visit Beuys up until the German artist's death in 1986.
Plus it also spawned Kraftwerk – the emotionless techno-pioneers bringing their "folk music of the factories" to Tate Modern from today until next Thursday (demand for their eight concerts broke the gallery's website).
However, if one thing can be blamed for the Altstadt's hedonism, it's Altbier.
Such is the parochial pride in Altbier, I spotted everybody from chicly-attired businesswomen to grisly-looking Rammstein fans supping the refreshing sharpener over the course of a weekend.
Afterwards, I squeezed into matchbox-sized parlour Et Kabüffke to sample Düsseldorf's other local elixir: Killepitsch, a 42 per cent liqueur made from 98 different berries and herbs that tastes like Jägermeister-infused Ribena.
Paul Klee lived here during the 1930s, teaching at the Kunstakademie, the art institution responsible for both the world's top-selling living artist (Gerhard Richter) and the artist who snapped the world's most expensive photograph (Andreas Gursky).
A ubiquitous local beer which tastes of bacon, it's served in tiny, 200ml glasses (it apparently deteriorates quicker in larger tumblers).
I first sampled it in Zum Uerige – one of five pubs in the Altstadt that brew it on-site – alongside German pensioners of the singing-songs-and-clinking-glasses-variety.
Adopted by locals in the 19th century as a way of subverting the reigning Prussians' love of punctuality, the five-day frenzy is held every February and features a gargantuan parade plus women slicing off businessmen's ties in exchange for kisses.
Düsseldorf has cultural cachet, too, with over 100 galleries (not bad for a city of 600,000 people) and imaginative "starchitecture" (see Frank Gehry's oddly-shaped Medienhafen office buildings and Daniel Libeskind's forthcoming Kö-Bogen shopping centre).
Defying its international reputation as an industrial conference hub, most Germans regard the city as chi-chi and haughty, thanks to its prosperousness (the only debt-free city in Germany), high living standards (sixth in Mercer's 2012 survey) and the boutique-lined Königsallee, where Claudia Schiffer was discovered by model scouts and Russian tourists head for weekend Gucci-snaffling shopping sprees.
