This museum is so massive. A vast array of interests catered to, anyone can find an area of interest. Get a map on entry & choose areas or special exhibitions to get more from your visit. Entry by donation, is a sweet idea, whatever you choose to pay, you will leave satisfied. The rooftop restaurant is said to serve great food & offers lovely views. Unfortunately we could not make it as it shut due to rain. But said to be pricey too.
