Everyone at your table is painting the same scene and every canvas is going to come out different, and at some point somebody will say it's over nine thousand and the whole room will groan and not one person will actually be annoyed.
That is the appeal. A fan-organized paint night with an instructor walking the room, a predetermined anime subject, and every material handed to you, so the barrier is zero — you do not need to be able to draw, and nobody is judging the proportions on your Goku. What you leave with is a thing you made and a table of people who needed none of it explained.
The brewery in Long Beach keeps the beer and the food coming, cosplay is fair game, and these sell through ahead of time.
Bring the friend who insists they cannot draw. That is precisely the person this was built for.
