Remarkable in the true sense of the word, that is: worthy of particular regard, respect or consideration compared to others.
In fact, this restaurant is notable for its location with respect to the city center (in a side street 500 meters from Hagia Sophia/Blue Mosque); notable for the quality of the food; just as the education, diligence and professionalism of the dining room staff is noteworthy; the friendliness and pleasantness of the owner is more than remarkable; but above all, notable for the competence (particularly of the owner) in knowing how to manage the particular dietary needs linked to celiac disease, in a country where it is difficult to find places equipped in this sense since (good for them) this problem is not widespread.
Finally, their habit of offering a dessert at the end of dinner is noteworthy.
The only thing I didn't find remarkable was the final bill, which I instead found decidedly honest and moderate!
As an expert contributor, I HIGHLY recommend this restaurant.
