The foundation of the Kizilkayalar Hamburger is in 1970s. In 1978 it was taken over from Haci Resul Bey and its name was changed as Kizilkaya which is the surname of the new owners. Later the company name was changed as Kizilkayalar Hamburger.
Due to the increased number of the people that visited Beyoglu, the buffet understanding which is faster and cheaper, entered Beyoglu. On these days all the buffets in Beyoglu sold their products like lahmacun, su boregi and tost but Kizilkayalar started to sell doner to its valuable customers. Doner at these times was 5 kg so it was over at 6pm. All the buffets around Kizilkayalar started to sell doner but this wasn't a lucrative business so they offered Kizilkayalar to sell the it together. Kizilkayalar didn't accept this offer moreover they produced more doner to increase the daily selling and continued to sell doner until 9pm. Also it was a disadvantage, Kizilkayalar sold doner until at 00pm and from midnight to morning, they continued to sell. Other buffets started to put doner their buffets after Kizilkayalar. After a few years, doner becames a sector and Kizilkayalar becames the founder and the leader of this sector.
The name of the doner was heared in all Istanbul and people knew that they can eat doner in Taksim whenever they want. Anymore, doner became important fast food of Istanbul. Doner was the innovation from the Kizilkayalar to Istanbul. The important reason of the fame of Kizilkayalar Hamburger is being the first presenter of doner.
After some time doner entered to all the food companys' kitchen and they started to sell it. As Kizilkayalar we knew that we must find difference and this idea helped us to create Kizilkayalar Hamburger.
Kizilkayalar Hamburger existed all the time but we changed the sos to present difference taste to our customers' palates. Also this sos was imitiated by the other buffets too, but they couldn't catch the Kizilkayalar Hamburger's original taste. In the end, we presented the special sos that can not be imitiated to our customers. We decided to intensify to hamburger. That's why we converted our name from Kizilkayalar Buffet to Kizilkayalar Hamburger and patented this name. A Turkish Hamburger accessed conspicuousness of other foreign hamburger producers. The important reason of loving Kizilkayalar Hamburger is that producing by people who know the Turkish palate.
A questionary which is on the way of customers' palates in Turkey, Kizilkayalar Hamburger passed the important hamburger producers in the sector and show its power in hamburger.
