The Metro isn't as bad as people make it out to be. I rode for a year before I brought my car out here and it doesn't take that much longer to get to where you're going. Especially if you factor in finding parking. Haha.For everyone else, I'm sure you can find nicer and more reasonably priced alternatives a little ways away. Downside is you need transportation and/or dealing with LA traffic (It's something you can tell the folks back home about!).
I believe the Gold and Expo lines have recently opened their expansions. Not that Gold will be used by many E3 goers, it's fairly far. But there's some amazing Chinese food off that line.
