I went to Turkey for a study abroad when I was in college. The best thing about Turkey was definitely the food. I love the food!
It's kind of a mix of everything that's in that region. Turks eat white bread similar to Italian bread, that's their staple starch. And they have a variety of cuisines through the country.
I traveled to a province in Eastern Turkey briefly called Adana, and they eat a lot of meat there. In the East, there was a lot more variety for vegetarian dishes, lots of salads and some common foods with Greek cuisine. You can find baklava, stuffed grape leaves and lots of yogurt in Turkey. In Northern Turkey, near the Black Sea, fish is a major part of the cuisine I believe.
