I went with a party of 12 on a Friday night. The kitchen was closed for renovations so my friend was instructed that we can bring outside food (just no alcohol). It's great that they informed my friend of these rules or we would starve.
Rooms are clean. In Room 9, the seating couch goes around the room. However, 1 seat in the corner was fully taken off so we were missing a seat. It was awkward because there was an empty space. We didn't have enough seats around the TV's so a few of my friends had to request for chairs. Uncool.
Their selection songs are okay. I love that most of their songs had the original music video playing. If you are expecting new songs, don't count on it. They have great variety of music (pop, Kpop, Chinese, oldies, etc).
I would definitely go back on a half year basis. It's nice to sing and act silly with your friends in a private room.
