^ Hell, let's all get beers!
San Diego is big, very big. Style depends on where you go I suppose. Downtown is full of bums and yuppies. North Park is full of boutiques and hipsters but a LOT of good art and music seems to emanate from there. Chula Vista and South Side is a mix of a more A&F attire or flat out gangster chic, from which I have bastardized my style from. Ocean Beach is all CHILLED out hippies and Pacific Beach is frat boys and Juicy girls.
Yes, I'm generalizing, but I'm about 90% right. That's still an A- on a report card right? I think the best thing to do is follow art shows and different bands around as there's no definite 'cool' spot.
