Statue of Liberty and Ellis are great to see and will take most of 6 hours to do, but well worth it. Ellis is unbelievable what those folks all went though to get here. To get into the base of the Statue you need a free ticket as well as pass through the machines that blow air and sniff you and that's after a typical airport scan before being let on the ferry boat. Call or web over to the Circle Line for tickets. Ground Zero is a must and close to the Statue ferry dock. Go after Ellis Island.
Bond 45 on 45th between 6th and Broadway was the best meal we had there. Excellent Italian - softshell crabs, veal picatta the size of a pizza.
The oyster bar in Grand Central has clams, oysters and mussels from all over the world - interesting varieties I did not know even existed.
