Where does the African community hang out in Istanbul?

Hi, my name is Gregor and I just arrived in Istanbul. Well just arrived s maybe a bit too simple I live in Istanbul from January 2016 but I have the feeling that I am getting to know the city (on the European side) a bit now.

In Holland where I come from I just to hang out with people from Africa like Uganda, Rwanda, and Suriname, Curacao, Aruba. Why because they are the friendliest people in the world. They are warm and good for spending time with and I love their food

Can anybody help me with some places where I can find restaurants or bars where the above mentioned people hang out in Istanbul? Or are you from the above mentioned countries contact me direct
