any suggestion on a nice live jazz club? (Seoul)

Hello, members.
I signed up quite long time ago but haven't been able to participate in any of the events yet. I will try my best to make it to the next one to say hello to all in person :)
Just wanted to stop by and say hello.

anyways, can anyone recommend me any nice live jazz club or bar in the city?
One thing which I can't live without... :(

Any locations will do!

Thank you all..
