Karaoke World is an outstanding establishment. The sheer size of its rooms, the selection of music that is available, and the well-stocked bar puts it well above some of the other karaoke joints in Sydney. Ding Dong Dang is fun if you want to be seedy, but if you've got a huge crowd of work colleagues kicking on for a song...this place is your best bet.
Had a good selection of English songs, unlike most other Karaoke places I've been to. Songs were easy to search for and the food there was pretty yummy, especially the chicken wings.
