Good karaoke place if you know where to look.
This place is hidden and I've only been here twice when my friend's bring me here.
They have private rooms and have songs in Korean, Japanese, and English. The service is always friendly and you can have free drinks (only water, hot/cold tea), even during happy hour.
Just to let you know, the Japanese and English is in midi format and you have to adjust the keys sometimes to get the right tone. Also, the lyrics go faster on screen but stick with how you know the song and you'll be alright.
