Besides 3rd Space there are also places like Co-Merge http://co-merge.com/ and the Hive http://www.hivehaus.net/ where some startupy types are sometimes. There is also an HTML5 meetup.com group.
I was mainly wondering if there are notable startups that are based there and/or if there is a strong community of people working the startup life.
Some solid Tech Meetups: - OC: http://www.meetup.com/OC-Tech-Startup/ - LA: http://www.meetup.com/Los-Angeles-Lean-Startup-Circle/ - SD: http://www.meetup.com/SanDiego-Tech-Founders/
I'm down in Orange County so I'm more involved in the community here with startups such as Mavenlink, Catchfree, and Drumbi. If you're going through LA, I strongly suggest stopping by Coloft.
If you have more questions or anything, let me know.

Very interested in finding groupings of web-oriented startups, designers, developers and entrepreneurs to plug into. Please keep the links coming and thanks... Looking forward to it! :D
Due south of Santa Monia, in Playa Del Rey and Marina Del Rey, you'll find gaming giants (like EA and Activision) and gaming indies.
On your way down to SD, you can stop by Irvine, which is pretty famous for its biotech scene.
Throughout SoCal, you'll come across food trucks. They did not actually originate in SoCal, but they did take off here. Sites like Foodtrux and Truxmaps can help you track down nearby trucks.
Consider using Meetup to see if there are any tech-related meetups happening during your trip. There's usually at least one or two each week. Also, the Miliken Institute has a startup-related panel every month.
