Yum. Yum. Yum. Not sure what else to say. :)
You can get Doner Kepap's (they spell it with 'p's! ) all over Istanbul. We probably ate them...two or three times...or maybe more. :) I don't remember.
If you haven't had a Doner Kebab, you need to try it! It's not just chicken, but other meats too, if you have an adversity to chicken. They put it inside a flatbread with vegetables and a mild sauce, then toast the bread.
As I said before...YUM! :)
