There are two primary Karaoke shops there, and the good one is on West Charlston..
They carry a Lounge paper, that lists most of the venues available.
Many clubs sing 7 nights, but all of the clubs are listed..
The clubs that are doing well, will have an ad..
(The second Karaoke shop is primarily Filipino based.. Inkjet printed)
Back in the day, you could sing to a live band at The House of Blues.. Not sure if that's still available..
