Finding this place is easy enough. The problems start when you're stranding in front of the door…read moreand realise that you really have removed yourself from the tourist hot spots. No English in sight anywhere.
First issue is how do I get in. Well, if there is a key in the door then just enter. It's looks more like a private home then a restaurant. But it's alright. You haven't by mistake entered the home of a Turkish family. Don't mind the gigglish girls inside, just find yourself a table.
Next issue. The menu. There are a few pictures, but otherwise knowing a few Turkish words will be helpful at this point. If you don't, then point (your waiter has a very very limited English vocabulary, but he is more than willing to help) and hope someone in the restaurant can help you a bit along the way.
Expect the food to be Turkish breasfast with limited spices, but an otherwise very nice selection of primarily Turkish produce.
