Spot was suppose to be a great place to go out, but it all depends on what night so make sure you find out what type of music is playing that night also it is a little ways off the main strip of Kassel so be prepared for that. The best time to go is Tuesdays before midnight till when they serve beer for 50 cents.
Check out the area around the Hauptbahnhof. There you will find Clubs like the ARM and the Cuba club two of the most favourite clubs in Kassel at the moment.
