I have been on it a few weeks ago.
We had a bit of a heavy night and I thought it was just some sort of theme pub near Kult Fabrik.
Next thing it set off!!!
Very cramped and no toilets and he didn't stop until he got over to
Karlsplatz.
We got off there and ended up getting a rather expensive taxi home (which would have been half the price if we had not got on)
