Probably your best bet for Asian karaoke! The only other places I knew that had private rooms were Korean BBQ and Saketini, and I heard Saketini doesn't do the private room karaoke anymore. Who knows... they may bring it back!
But as for August, it's pretty nice. It's also pricey if you don't have a large group to divide the hourly cost! The setup is nice. Each group as their own room. You can even rent the large open area in the middle of the place. I do like how the song selection is all digital and has nice pictures of artists on it. It's very modern app setup. The rooms can fit up to 20 people it seems, and you can bring your own drinks and food.
Selections of songs range from Thai to Korean to Japanese to American songs... a little something for everyone! And it even has some pretty recent songs. I think the best part of the digital interface is that you can choose five to six different ways to find a song. Genre, artist, language, title, top hits, etc.
If you have a large group that wants to sing privately, this is the place. Of course don't make it too large because then you would only get to sing one to two songs every hour.
