Q is always a fun place for karaoke , they have different size rooms to accommodate various group sizes.
The rooms are nice and they have party mood lighting that is spazzy that gets me into the karaoke mood. Music is ear deafeningly loud but its fine.
The only problem I have with the place is that the cordless microphone seem to periodically keep unsyncing but the staff was very friendly and helpful with this problem .
As for price it is super cheap we stayed about 3-4 hours in a large room and got yogurt soju, beer and snacks and we only paid about 16 per person split among 10 of us .
The people there are friendly food service and music is good , only downfall is the mic connection . Screws up my groove. :(
