I only discovered this place because of a friend's recommendation. It is not the easiest place to find as it is on the 2nd floor of a popular market and they only have a very small sign on the ground floor. To steal a quote from Zoolander, "it's so exclusive nobody knows where it is."
Once you do find it you are in for a real treat though. On Monday nights they have open mic night, but not just for any goon with a guitar, you need to be talented and boy are they ever.
The music was mostly (as the name would suggest), blues; which is actually a very easy type of music for musicians who have never jammed together before to get together and play quite well on their very first try. This is because there are certain "standards" of chord progression that exists across many of the songs.
You never know what you are going to get on a Monday because the lineup is always different. I was in for a real treat on the random night I attended because a trumpet and harmonica player who had toured with the Rolling Stones were in attendance.

The owner of the bar is nicknamed "Boy" and he is an extremely talented musician that is also very approachable and friendly. When he is not on stage he sits around the audience and has a chat with the attendees. By the end of the night it was standing-room-only so if you enjoy blues, or simply live music in general, this centrally-located establishment is well worth the difficulty you might face in actually finding it.
