Kirklar Kilesesi (Church): Good Bet for Wine
This is not a shop. But if you are visiting the Kirklar Kilesesi Syrian Orthodox Church in Mardin, the young wife of one of the church officials there may offer you some homemade wine. They sell it there, and it is well worth the price. This bottle of Syrian Orthodox wine was one of the best souveniers I brought home from Turkey. Alas, it didn't last long!
