You can find Karaoke-Bars everywhere around Boat Quay, there is one bar next to the other. At your table, you get little notepads on which you write your choice of song. Then after a lot of chinese songs youmight be lucky to sing one. I had the impression that everybody there could sing really well but we just shouted (also because of some beers :)... For some reason our performance was so good that one local paid a jug of beer for us. Thanks
