What food can you get at 1am in your area

Nothing in my neck of the woods but Jack in the Box nearby. If you want to drive a bit you can find a Shari's (a downgrade from a Denny's).

@autoxcuda, I'm with you on Tommy's. I'd make a point to stop at there after a show in LA on the way home to Anaheim back in the day. So what is an OKI-DOG? I checked a few photos but it's not clear. Looks like a burrito with two dogs, maybe pastrami, and what all else?
