This has to be at least 20 years back, probably longer. We had one in our local mall. They had someone in the front window making some sort of flat bread on a small round pan. The bread itself was a bit thick, round, but had a crispy outside and a chewy inside. Not like any of the flat bread I've tried since. And it was slightly sweet. I always got the lamb gyro minus the onions but with the wonderful garlicky, sour cream cucumber sauce.
At any rate, I'd love to find a recipe for the bread they were making, but I can't even remember the name of the restaurant.
Does this ring a bell for anyone?
