I reserved a room for karaoke for twenty for a birthday and I had a great time. We had people under 21 so we didn't really have a host, but everyone enjoyed themselves. No one showed us how to use the machine, but we figured it out. They served water which was nice. They had a great selection of music including newer stuff.
We did order drinks at the bar and I thought it was very affordable. I got a bottle of soju for like $20 which is 6 shots of liquor.
The room was affordable for the amount of people. I believe it was $40 an hour, but they do have cheaper rooms for less people.
Overall the staff was nice, the bathroom was clean, and I would definitely karaoke here again.
