Do Impressive former mansion of one of Turkey's richest men. It's a small museum but boasts amazing views, one of the world's best selection of Ottoman calligraphy (if it's not traveling), special exhibits (had a memorable photography exhibit about what blind people saw last when I was there), as well as a great modern cafe.
