It's not tasty. If it is expensive and tasty in Russia, then it is expensive and not tasty here. By the way, there are no sauces, they traditionally serve mayonnaise with ketchup everywhere.
I took a combo double cheeseburger = 265 lira = 795 rubles, multiplied by 3
If you can eat a burger, it's just not as tasty as in Russia, then potatoes are a horror.
The burger is small in size, I can't compare it, since I didn't buy a double cheeseburger in Russia.
