Though it takes places in Ontario, CA, it may still technically be in LA County. It's Anime Los Angeles. The first anime convention of the new year is really a huge fan get-together. The main thing is fan events, but this year we see a lot of voice-actor signings and panels.
Breaking it down, you come here to listen to other fans and meet other fans discussing anime in panels. This year they have quite a few panels with English voice actors from your favorite dubs too.
For those 18 and over there's some stupid and silly panels like Hentai Worth Reading and other dirty and perverted stuff a little bit after 9pm every night. For those just entering college or the last year of high school you"ll laugh at what dirty side of the internet has to offer with your fellow Otaku.
As always, go through the schedule for something specific you might want to attend. There's something for everyone from PC/ Console/Board/Card gaming, karaoke, cosplay to just chilling watching anime and reading manga.
