Definitely Yengec, normally you have to book in advance - number available on their Facebook Page and also I believe decide what you want from that night's (as in the night you are going) menu in advance.
Shine too, my favourite Indian anywhere locally.
Also Yakamoz. They are a bit off the main road before the new Jandarma station as you enter Ovacik and not sure if they do transfers but they have a nice menu.
