Harry Ghatto min Emirates Towers! Proper Japanese karaoke bar - they do good food too! BUt it does get extremely busy. They crank up the karaoke in the main room at about 9pm, although they do have a private room you can book too.
It's got a great atmosphere and gets really funny as total strangers start doing duets and stuff.
