Greek street food gyros comes to my mind!

A versatile food that comes in different forms. Basically you can get it either with pork or chicken.
Then you can ask for double pita.
Then order it apo ola (meaning everything, tzatziki, tomatoes, onions, even chips yes potatoes)
Or xoris (without) .. things you do not want inside your gyros.
Do not be confused with the souvlaki which comes from a stick.
Gyros is shaven meat and funny few gyros shop these days use electric knives.

For me its always APO OLA.
