Came here Saturday night and it was super busy. We noticed on the sign it says you cannot get in without some form of ID. With permission from the manager, we were able to get in without one person having ID (we were not drinking alcohol anyways). We get to our room and the waiter set us up with the machine. The system works such that you have to download their mobile app to select and change songs. You also have to use their WiFi to use the mobile app. Now, their WiFi is not good - there were times where it is so slow and it disconnects. The app also sucks because it lags and sometimes (40% of the time) crashes. Once everything works though... its alright.
Service is slow but only because they were super busy (full house that night). Its unacceptably slow and they need to hire more people for sure. But at least the people were very nice and apologetic for the slowness. Our food arrived like an hour later and the manager personally apologized and took care of us by putting all the food we order on the house. Although this place is not the best karaoke place I've been to, the people are nice and tried their best despite the busy and probably stressful night. If you don't like slow service, don't come here on weekend nights - it will take long for you to get food.
