The Morisson Club is one of Viennas most popular insider places. The Morisson is a very arty, bohemian and urban music club located in a former brothel in the trendy Naschmarkt neighborhood. It has the vibe of a hip underground club in Berlin. The tiny place offers a bar and a seperate room with a dance floor - dancing poles from the original place included.
During weekdays bar is open until 2 am, on Fridays and Saturedays there is usually party till 6 am. Apart from the usual DJs there are sometimes even small live acts squeezed in this place. And this place is really small. If a party at the Morisson is crowded with the local hipster community, you really get in touch with lots of people.
The Morisson Club very often features pictures and paintings from local artists. Apart from that the Morisson owners even operate their own indie record label. You can watch their promo video - which was actually shot in the club - at youtube: http://www.youtube.com/watch?v=HKqyPQ-aw_o
