Das Bett

Small location with fairly good sound system. Great for small concerts and music gigs since you get very close to the stage.
They have a small bar in the back with decent prices for drinks (e.g. 4€ for white wine, 3,50$ for Red Bull).
I came here for the Melotron concert last weekend and had a good time.

I loved Das Bett. It has an underground house/rave feel about it that makes it a breath of fresh air from the usual clubs. It just seems like that dodgy underground dirty bar where you meet the most colorful people, and have the craziest time. Really enjoyed it.
