Aegean dishes in Istanbul at Sidika

I'm looking for 6 excellent meals in Istanbul for my 'layover' so to speak. I have read some good reviews from this small restaurant in the beşiktaş area. It does not have anything special but apparently the simplicity and flavors of the dishes are worth the try. Now, I'm more curious
about the area (beşiktaş), in the European side of Istanbul and not one of the main touristy areas. Worth some research..
