Jesus, I leave on page 1 and we've progressed 4 more pages?
I seriously think you need to go to a scenester-ish bar. Something chill. No ridiculously loud dance music. (Not that it's bad, but you probably won't find what you're looking for at a typical bar/club.)
What about shows (as in, like, bands playing... "concerts" but smaller)? Back in my single days, I met hella people (girls/guys, friends/morethanfriends, etc) going to shows back in my younger, wilder days... Great times, decent music. Actually, it was shitty music with a random good band thrown in, but it comes with the territory (St Louis

). More importantly, it was crazy social times I was not prepared for but rather enjoyed. And you always run into the same people all the time.
I dunno, never been to the West Coast. Don't know what in the hell there is to do there. Just don't go in with the intentions of finding a girl and proceeding with becoming friends with them. If you see a girl you're attracted to, fucking play on it.
