San Diego's good weather attracts lots of tourists, but very few of those outsiders know more than the downtown. We do have funky/ethnic neighborhoods, Old Town places, and the similar. But only locals know about it.

in addition to all that, it was also the setting for the movie Anchorman, which i still laugh at after seeing it WAY too many times.
