I'm heading east to the Mission Tiki Drive-In in Montclair this weekend. (If you don't know it, it's well worth checking out. So few drive-ins left in SoCal, the home of car culture -- but that's another topic.) I want to pick up food along the way. Any suggestions of particularly good takeout, suitable for easy in-car eating, and not ridiculously far off my route? I'll be taking the 10 from downtown, so that covers a good bit of the San Gabriel Valley.
