When i visited E3 (May 2006) i visited LA as well
Universal Studios: nice, but very old as well. Quite proud of their 60's and 70's movies.
Santa Monica Pier: what's it about? It's boring. Watching beggars putting on their iPods is funny, but the pier itself is just.. a pier.. whoopee. Good fish restaurant at the end though.
I really hated the traffic jams three times a day. People said to me that everyday 9 million people are in the traffic jams.
LA is HUGE. (Hey, i'm from the Netherlands! ) The people are very friendly. The cheap food sucks, the expensive food is doable.
LA is devided in big areas/blocks. Poor block, rich block, poor block, rich block, etc. Blocks are boring, driving through LA is boring, poor blocks are scary. Rich blocks are clean, but no fun.
