Before Au Bon Pain and other chains took over LaGuardia Airport, there was the Airport Coffee Shop. This old menu, from 1941—about two years after the airport opened—was uploaded by the NYPL, who pointed out the Peanut Butter & Bacon sandwich today. That offering went for .15 cents (the same amount as a regular PB&J!), and while you can probably still find something like that on menus today, there are some other things you probably wouldn't be able to—like, say, the diced tongue omelette (.85 cents) or the fried ham/egg/relish sandwich (.30 cents).
