One of the, like what, two? maybe three karaoke locations in the valley? Aside from this place, there is like Aqua (overpriced), forbes (when its open and definitely overpriced), and XO by UNLV (old...)?
This is one of the "best" central locations that widely popular for karaoke needs. They have a variety of rooms available ranging from Small to Large and the VIP (x-large essentially).
Prices are decent, especially when split with people. Big selection for ENGLISH and KOREAN music. Old selections for Chinese. So you can kind of tell what kind of audience/clients they get.
They recently upgraded their system again but still limited selection but VERY up to date on music (includes recent album releases and movie OSTs like SNSD's Mr Mr or 2ne1's Crush to like Let it Go or Do you want to build a snowman from Frozen)
HUGE selection of food now as well as their drink menu. They've been having an on-going special of buy 2 get 1 free for flavored soju. Yum :P
