....... The ones I am familiar with seem to close early on Sundays, like 2PM-ish. If anyone knows of any SoCal airport restaurants - fly in and park close by - that are open for dinner on Sundays, I would appreciate the info!
Casa Machado at KMYF is open evenings, only one I can think of off the top of my head. Good place to go when the Mexican Low Level Light is illuminated.
