As far as finding spaces, I've found that local bars/restaurants/coffee shops are usually quite happy to host events during off-times like Monday through Wednesday nights. I always ask nicely, thank them in the event description, during the event, and in an email after, and try to go out of my way to make things easier for them (checking in with estimated attendees a few days before, helping put chairs back in order afterward, etc.) It's nice because these places are inherently social so people feel more comfortable talking, you don't have to worry about food/drink, and it brings attention to community-minded businesses.
