Which Hollywood open mic nights have the best atmosphere for newcomers?

[discoverhollywood]

I'm looking for welcoming Hollywood open mic nights where both performers and audience members can enjoy a relaxed environment. I'm open to poetry, acoustic music, spoken word, or stand-up comedy.

While searching, I came across Discover Hollywood Magazine, which highlights several local venues hosting weekly open mic events. Before choosing one, I'd appreciate real experiences from people who have visited these spots. Which venue has the friendliest crowd and the best overall vibe?
