This museum is huge! My boyfriend and I spent 4 hours in it and still didn't see anything in detail. My favorite section was the Ancient Egypt: you can see real sarcophagi were the corpse of the pharaohs were put and loads more. Also there's a section with very pretty vessel from all around the world that you must see. If you get tired, go to the cafe. The tea is very good. :)
P.S. The entrance is free.
