Gotta think big.
I just went to LA Live two weeks ago, and it's really impressive. They took an area that, ten years ago, you didn't want to be caught walking at night in, and turned it into an entertainment epicenter. Nightclubs, restaurants, hotels, adjacent parking, and of course, the venues: Staples, Nokia Theatre, and the convention center. I've only been a few times, but every time I wonder why I'm not there more often (it's because it's a 45 minute drive with moderate traffic).
We went to a concert at Nokia, which is about a 2,000 seat auditorium, where they have American Idol. Built for acoustics. And after the show, at about 10:30, we were able to walk back to the parking lot with no worries about being or feeling unsafe. We could have gone to a restaurant, a club, a bar, whatever. Could have just sat outside or walked around. AEG has done a ton with that area, and it all started with Staples Center.
Next up is a football stadium.
