Potato Republic (Istanbul)
I received an email from Erdal in Istanbul, Turkey. Apparantly, way back in 2006, he opened a shop selling different kind of potatoes. It is located on the outskirts of Istanbul in an area called Beylikduzu.
No idea about the quality of his fries as I have not visited his place yet. Judging from the pictures on the (Turkish only) website, they are frozen fries, not double-fried Belgian style, so for the moment I will not classify his business as a real Belgian Fry shop. But I understand Erdal wants to move on and concentrate on a Belgian Fries type of shop.
If anyone has more information, please let me know.
