It's a super place! There is quite a good supermarket in the historical quarter with a good assortment of not only cold cuts, cheese, milk, baklava. There is wine and other drinks.
Very convenient location.
It's not the cheapest chain in Turkey, but the range is certainly good, taking into account local needs of course. For foreigners, probably many products are not known and are not needed. But just to broaden my horizons and out of curiosity...
