The place does what it says on the tin. First thing you get when you open the door is a room with a ping-pong table (in very good condition, btw) where people play while having a beer. It's very fun to watch or play, don't be shy!
They also have some couches where you can sit down and have beer with your mates. Music varies a lot because during the week they have amateur djs like yours truly.
The place is very Berlin-esque, thus cheap and nice.
