Madam Tussauds Istanbul
Museum is not located in a hidden place. Easy to find there on Istiklal Avenue. I got some interview with Einstein. He is not a chatty man. :)
If it happens a guided tour and if the guide mention some interesting stories about the well-know people i think it might be more interesting.
I can swear Marilyn Monroe was REAL. This was my first visit to a Wax Museum. İncredibly amazing. There were some local artists as well who i dont know. Anyway i didn t spend my time for nothing. It was good
