If it was the worst meal you have ever had in Turkey, why did you not complain, or ask for a reduction on the bill. Surely you did not just eat up, pay the bill and walk away?
I think that Dogan & Nichola will be very upset that you did not tell them at the time of eating the meal that it was not to your liking or that there was something so terribly wrong.
I do not think you had caught them on a bad day, they do not have bad days.
We have eaten here many times and have not had one cause to complain.
