I know that we have pretty much exhausted this subject, but I had an encounter last week which supported previous posts about the authenticity of Arkadash's food.
I needed to fix the breaks on my car, and didn't have much time. Just like I support the local food establishments, I decided to support my local mechanic. Anyway, my local Mechanic turned out to be turkish. We talked about backgammon and apple tea for a while, and he recommended Arkadas Cafe as the best place for Turkish food in Chicago.
When I came back to pick up the car, we talked some more about backgammon and he told me about a turkish cafe on the 1800 block of Irving Park where some turks hang out to play backgammon. He invited me there to go and play a game. The place is only marked by a sign that says "internet cafe". Once you go in, you get transported to Old Istanbul. They have 6-7 tables filled with middle aged Turks smoking cigarettes, drinking tea, and playing backgammon and cards. We talked some more about Arkadas, and again, it came highly recommended.
Now back to the Mechanic, his name is Alexand his shop is on Ashland and Lemoyne (a block south of North): 1451 N. Ashland, he was quite honest and relatively inexpensive (I hope). Though I am concerned about going back there since I beat him really badly in backgammon.
