I've been here previously times and I'm not that big of a fan. I don't like karaoke for one thing, but that's besides the point.
The room we were in had really bad feedback on the mic. It kept interfering and causing that awful "buzz" noise. Plus the location of the machine was just above when you see what numbers you entered so you either have to have good eye sight OR you have to get up close to make sure you entered the right number.
The songs itself are pretty updated. You can even request for a Spanish book as well. They have a menu for ordering drinks and saw they had a promotion on their alcohol so follow up with that if you're interested. They don't allow outside foods or drinks.
If you check in through Yelp you will get a free sake bottle. Just show one of the workers and they will follow up with ID checking. The only problem with that coupon is it is misleading. It says PER PERSON not per party so after I redeemed mine I told my friend to do it as well. She had shown the worker and had already clicked on redeemed. The worker said they allow one per party because if everyone redeemed it we would have 20 free bottles of sake. He later added on that they were meaning to change that coupon, but will honor it for now since she already redeemed it.
All in all, this place isn't bad to go if you don't mind singing your hearts out while getting drunk.
