Don't bother going until 2015 which is when the reconstruction is to be finished. They have no exhibitions open since hurricane Sandy, except for some fishaquariums, walrus & seals. Waste of time.
The line in the cafe is ridiculous. I am waiting about 25-30 mins just to get a water and coffee. Slowest service I have ever encountered. There were only about 10 people in front of me too. :(
Very short day. Wasn't much to do here. It wasn't very expensive but we were done in 1.5 hrs. That makes it better on the little ones with short attention spans.
