The crew I was with went to Karaoke Q twice in a week! The food was great, a room of 10 people made the charges relatively low ($33 per person the first night, about $53 per person the following visit.
The room has two microphones in it. The only downside is the karaoke song list is more limiting than some of the other karaoke bars that I have been too.
It's very nice to have your own private room with cool lighting and a full-screen projector for the lyrics. You can get up and sing as often as you want and not have to wait to be cued up by the DJ.
