I've been here a handful of times recently. It's a great place if you're in the mood to sing your heart out in a private room without the uncomfortable atmosphere of strangers watching you during public karaoke sessions in bars.
Yesterday night (Saturday) my friends and I went. Although it was quite busy, they gave us an extra 10 minutes (usually they charge 25$/hr on weekends). We had difficulty using their gigantic remote control so make sure you ask for help before you waste your time figuring it out while your precious singing time is going to waste!
I would come back here on a weekday because it's less busy and so they're more willing to give you an extra hour or so, like what happened last time I went on a Monday.
3/5 stars only because the atmosphere is subpar compared to other karaoke joints (ie. TEN23, Bar+ Karaoke)
