I had a blast at this karaoke spot with my friends. However there is a limit that u must spend for a room but it is also unlimited singing time so you can basically stay for as long as you want. I love that they serve food/snacks so you basically get your money's worth with food/drinks while singing.
The only downfall would be the karaoke system. Its all in Chinese and since I am not Chinese, it is a little hard to understand/use but I managed to figure it out. They don't have as many of the new english songs that I wanted to sing but there were most. I do wish the audio was louder in the rooms tho lol. Also, I only saw about 4 rooms so if you're looking to rent a room I suggest calling them as soon as they open (8pm) to reserve a room. My group was the only one at the lounge that night so it was kind of empty but I didn't mind.
Overall, I really like this place because its a good place to hangout until late.
