This is an excellent museum. I've been to all the Smithsonians, the Museum of Natural Science in NY, and others and this one matches them all. The exhibits are unbelievable and comprehensive. It is a little overwhelming when you enter with all the choices, pricing, but it can become clear with the help of the accommodating staff. Everyone was so helpful throughout the experience. The food court is even great with good burgers, etc. A great day-long experience.
