Drive or take a bus to Malibu... around 30 mins away.

Eat at the Lobster, great restaurant right next to the ocean. If they still serve it: tuna and avocado salad.

Watch 100s of people doing 100s of different activities from chess to surfing, ultimate frisbree to yoga... you imagine it and there is probably a group of people there doing it. Maybe I am going over the top, but its a pretty diverse and interesting place. Oh and I never felt unsafe at night.

Hope that helps
