Spend too much time perusing the cute cafés in Brentwood and you'll miss out on the sushi bars and noodle houses along West L.A.'s Sawtelle Boulevard. Once you've discovered the great running path around Silver Lake Reservoir, someone will tell you how much you should be exploring the hills above Echo Park. The typical beach experience of Malibu and Santa Monica never gets old, but the mystery and cultural history of San Pedro are worthy, too. And what about Koreatown? L.A. is the ultimate moving target.
