I came here once. I was showing a couple of chicks from France around the city and they asked me to show them a place that would have some interesting/weird music. I immediately thought of Divan Orange and made a beeline there.
There was a band and they sure delivered. I don't think a genre exists for what they were playing. It wasn't great, it wasn't bad, but it was new and interesting, which is what I wanted (and more importantly, what the two French chicks wanted).
Several beers and 20 vodka shots later and dubstep was blasting on the sound system. We played a game where we timed each other dancing to dubstep in the middle of a crowd just standing around and mingling and whoever could dance the longest by themselves won a shot. I have video evidence of this; no one cared and if anything, the staff were amused. The bartender was not only a bearded man, but a nice bearded man.
I had a good time and I would come back again.
