I'm reminded of Bill Bryson writing about midwest food in the Fifties, when almost everything was white or brown and pretty much tasteless. Not a lot of difference in PA in the Sixties, though we had Italian food because we were near Philly. But chow mein was considered really exotic. All the stuff we'd never seen-- guacamole, pad thai, samosas, masala, gallo pinto, (veggie) sushi, Ethiopian food....

Excuse me, got to go help make the tacos.
