Did you try In-N-Out next to the airport? Great burgers. It seems that one of Los Angeles' positive claims to fame (besides the earthquakes, OJ Simpson, mudslides, brushfires, plagues of locust) are great burger joints. In-N-Out, Fatburger, Tommy's.
onedog, I did manage the In-N-Out in Azuza on Saturday. I'd been to the one in Vegas south of the Rio in December. Yum! I missed Fatburger this time - one burger a day is my limit!
