Apparently I'm not the only person out there who's stumbled upon this place but having been coming here for years now (about six of them) I've decided to bestow patron status upon myself and thus write a review to give it a shout-out.
If you've never done private-room karaoke, you're late, cause it's really awesome. If you think you need substances in your system in order to belt out some Killers or uh, Ace of Base (in my case), then they'll bring your adult beverages right to your room!
There's nothing more fun than doing private-room karaoke with a group of your friends and people can come hang out on the comfy vinyl couches whether they choose to grab a mike or not. The experience will cost you about $35/hour so the more folks you bring, the cheaper the bill - and you can stay 2, 3, 4 hours without noticing the time fly by.
I know I didn't actually provide any helpful information but bring cash, learn to search the menu by artist (the folks who work there will help you, as everything is in Korean), there's extra parking behind Max's (the falafel place on the end of the same strip mall), the staff are really helpful and will attend to your needs (new batteries for the mike, turning on the AC, searching for songs, etc.) and the place looks somewhat shady from the outside but is a perfectly great establishment.
Enjoy!
