I went to Emirgan Park and then to museum. This is also an event called "1800 years of Turkey" in the museum. I also had lunch at there, which is one of the local restaurant. It had Turkish fusion food. Then I went to Rumeli Castle. This has the best view of the bridge that links between the European and Asian side of Turkey and most importantly, the Bosphorus.
On Sunday, I went to the best mall in Turkey, which is called "Istinye Park". I did some shopping and had Italian food there. This weekend is probably the best weekend in Turkey.
