Best doner we had in Istanbul/Turkey! It's very far from the city center (about a 40-minute Uber),…read morebut it's very popular among locals and when the Uber driver saw where we were going he said, "Yes, that place is the best"!
The meat is super juicy and doesn't have the same gamey taste that is present at a lot of the other doner joints throughout the city. They also provide plenty of bread, toppings, and sauces. Despite its popularity, we didn't have to wait at all--the restaurant is enormous and has plenty of space for everyone, and any party size. It's a great place to sit and chat with friends, or grab a late-night snack (which is what we were doing).
I'd highly recommend checking it out if you have the time!
