San Francisco Movie Get Together?

[filmgeek20]

Is anyone in the SF Bay Area of CA going to make November 15th an 
"event?"  I was thinking of dressing up on that day to the theater but 
I do not know where all the "hardcore" Harry Potter fans will be.  I'm 
sure fans are everywhere but I don't want to come dressed up 
to some megaplex only to be gawked at by teeny boppers who have 
nothing better to do on a Friday night and *casually decided* to see 
Chamber of Secrets that day--know what I mean?  I would like to go to 
a theater that has HARDCORE HP fans.  Do any of you have suggestions?

I was thinking of going to a San Francisco theater at around the 7pm 
show.  Please let me know your thoughts!  Thanks! :)
