It's not in Çaliş but as there have been a few suggestıons now I would like to highly recommend the lamb shank I had at Aubergines in Ovacık last year.
They have three I think on their menu, one with mint which is the one we shared, one with pomegranate and I am sure a third option but I can't remember what if they did.
It was delicious, a very plentiful serving of tender meat, lots of gravy, mash potato, chips and fresh vegetables.
If it's up to the same standard it would be worth making the trip.
