One of the best, if not the best, view of the city. Sitting on the 67-69th floors of Rockefeller Center, you can see the entire city from here, including Central Park, the Empire State Building, downtown, the Statue of Liberty and others.
Quite a breath-taking view of the city. Just be aware if it's windy on the ground, it's going to be insanely windy up top.
Nice, quiet bar/restaurant in Little Italy. Nice bartender and tasty (strong) drinks. Fairly expensive, but the environment is nice, and it's close to a lot of other restaurants.
Amazing Brazilian BBQ restaurant... you know, the kind where they give you a stop/go sign and you eat meat until you can't eat meat anymore. It's expensive, but well worth the money.
While you're there, try the caiparoska (Kai-pa-ro-ska). It's a very strong, but quite tasty Brazilian drink.
