I brought a group of friends here having never visited before and had a blast.
The play list is mostly Korean, but even though we only speak English there was still tons of songs that we knew and it kept us entertained for hours.
I'd go again, but I'm going to try another bar simply because I'd be redoing a lot of songs.
Go. You'll have fun. Be happy to hear Korean singers. For some reason they take the edge off :)
