2-4 Rheinauhafen/im Zollhafen
What: The Cologne outpost of Frankfurt's famous King Kamehameha club is nightlife for adults with two restaurants (one casual, the other fine dining), two bars, and a lounge.
The look: Futuristic organic, with sleek wood floors, low swooping banquettes, and floor-to-ceiling windows overlooking the river. It's one of the most stunning lounge spaces in the city.
Who goes: Cologne's thirty- to fortysomething Schikeria (wealthy designer) crowd.
Sound track: Funk, soul, and top-of-the-pop-chart dance music.
What to wear: Deutsch designer Jil Sander's new collection for Uniqlo.
What to drink: Kölsch, a local light beer served in test tube-like glasses.
Door policy: Easyno bouncer. On Wednesdays a band plays, and the cover is $8 unless you're dining..
