The coolest after-dark attractions just have to be across the pond, don't they? I'm drooling over screenshots of Twentyfour, which looks pretty darn awesome (though who knows what the crowd's like). With over a thousand LED color combinations available, this is one place where the decor won't get boring--and did I mention the walls are actually projection screens?
The video walls kind of remind me of the Nokia flagship store in Manhattan, but from what it sounds like, they're a lot more functional. Bar patrons can control, or even contribute their own scenery somehow--I should point out that this could get bad if alcohol's involved, you know, "You bloody wanker, why did you put the rainforest scene up there again?" Some of the projections are even interactive, responding in one way or another if you touch them or hold your drink up to them ("Ooh, the fish swim toward my martini!")
Here's the part I like the most--lay a hand on the bar, and it'll alert the bartender that you need another drink. Those of us used to crowded urban nightspots where it can take a full ten minutes for the bartender to even notice your existence can attest to the gravity of this breakthrough.
