It's not a Karaoke "bar" (which I prefer as there is nothing better than watching strangers sing!) but Ding Dong Dang in Surry Hills is ULTRA popular. 6 people rooms are $30 per hour ($5 each). However, you can get rooms for up to 15 peeps, which makes for a load of fun! Otherwise I have heard tell of bar style karaoke at Chatswood RSL on Friday nights from 8pm, which has more of a down home relaxed suburbs flavour. Scruffy Murphys is another option. It is located in Golbourn St Sydney . Though not for the faint hearted it is a fun (read messy) night out! For a meal and karaoke try JuJu's in Kings cross, but be warned it kicks off late!.
