Cheers to lijie for bringing this one to my attention. She describes this open mic as being laid back, but having a really good vibe. The night's host, Eric, says,

"Have your guitars tuned up before hitting the stage, be respectful of your fellow musicians, and have your songs down! Those who have biggest crowds are considered for a Thursday night full gig."
