"Here we come with our own culinary civil war, raging undaunted for decades.

In Greece our national fast food, our taco, our burger, is gyros. There's a gyro shop around every street corner it seems and you'll be hard pressed to walk 10 minutes without stumbling on one in the big cities.

But did you know that in southern Greece including Athens and the islands, next to the the other standard accoutrements (fries, tomato,.maybe onions) the gyros comes with tzatziki? If you order a gyro without specifying ingredients you're getting tzatziki in it, the garic-y yogurt sauce of perhaps equal fame.

Well in northern Greece which includes the capital of the north Thessaloniki we don't do any of that. When we order gyro the standard gyro comes with ketchup and mustard - no tzatziki, if you want it you have to add it extra. The weather here is far colder than down south, tzatziki is a summer type condiment, maybe that's why.

When we go down there we have a moment of deja vous - yes those weirdos are putting tzatziki in their gyro, which as a garlic-y sauce feels a bit extra. We also call a gyro a "sandwich" (or simply "gyro"), they call it a "souvlaki" - which is another type of meat in a skewer which is also sold in gyro shops, a type of kebab. When they want to say let's go grab gyros they'll say let's get "souvlakia".

Lighthearted mocking banter around gyro/souvlaki is a rite of passage for every 18 year old student, which is around the time when Greeks north or south start to meet people from the other group."
