Harry Klein is one of those clubs that doesn't just try to be cool, but actually is cool. With a funky interior that is VERY intimate (ok... small) you can practically sit on the lap of some of the finest electronic djs around. There's lots of projections to keep your eyes occupied while your feet are moving to the beat, and if the weather is nice... the crowd spills out into the tiny attached beer garden. A nice night out, even if it's a local dj spinning and you can easily walk to the club from the Ostbahnhof stop.
