So there you have it, the premise of the whole comic :)

About what they’re eating: It’s gyro. (Yum.)

Gyros sandwiches in Greece, with meat, onions, tomato, french fries, and tzatziki sauce rolled into a pita

That’s your clue that the story is set in Athens, Greece. Most webcomics I read are set in the US. I’m all for using English to make the comic more accessible to more people, but I thought that I’d love to see something set in my own city.
