Balkan kitchen is one of the traveller’s choice kitchens because portions are big, delicious and cheap! So technically İstanbul is also part of Balkans, and assuming you had the itch to try Balkanian food in İstanbul, here is where you should go: The Bosnjak Mutfak.
“Mutfak” means kitchen in Turkish, so you immediately understand what kind of food you can find here! 
Opened its door almost 2 years ago in 2014, The Bosnjak Kitchen conveniently located in Etiler, one of the luxurious neighborhood of İstanbul offers many varieties of Balkanian food.
Of course when you think of Balkan kitchen, first thing coming to mind is Cevapcici and Borek! Here of course you can find these and many more specialties such as Begova soup, Sopska salad, dried meats and ajvar sauce and of course queen of desserts Trileçe and many more!
All food are prepared according to original recipes, they even use kaymak when making borek! And I was also told chefs were Bosnian women!
Decoration is cozy with nice color combinations, many small Balkan household items used as if you were in a Bosnia house! Music played is also Balkan music. I found all in all atmosphere very cozy.
Menu was very interesting! It came rolled up into rolling pin! Menu of The Bosnjak Mutfak has it all; from beginnings to soups, salads to main courses, special foods to desserts. It includes all the traditional dishes you can name.
Also if you are lucky or don’t leave it to luck and made a reservation for it first, you can also come across “tandır” which is a special meat dish which needs to be cooked more than 4-5 hours so it is not always available upon request. But it is better to order this if you are more than 2-3 people because portions is not for one!
Like I said The Bosnjak Mutfak is located in one of the rich neighborhoods of İstanbul so prices are not cheapest. But I found quality/price value high. You see if you have ordered these foods in Sarejevo or Belgrade it would probably cost at least %50 cheaper! But that’s because Balkans are very cheap!
As of April 2016, you can find Begova soup priced at 14 TL while Cevapcici (meatballs) is around 29 TL. Salads and boreks were around 14-18 TL as well.
Let me remind you that in İstanbul, in a good quality restaurant you can’t find meatball dishes cheaper than 25 TL, so considering location and quality I don’t think prices are too high for İstanbul.
They also bring bread, kaymak and ajvar pre meal. But I think later on a small fee is included in the bill for this.
By the way, owner Mr Mithat, (Mithat Erdem) is also founder of one of the most known and loved meat restaurant chains of Turkey, Nusr ‘et’.
