oOo! NYC! I <333 NYC. i'm going there thursday to see Rent.
anywho.. if you're going to NYC, I highly suggest going to see a Broadway show. they are AMAZING. Lion King, Beauty and the Beast, Wicked, Phantom... the list goes on and on. lol
and of course, Statue of Liberty, Ellis Island, Empire State Building are must sees. (which is kinda odd for me to say because i've never been to any of them... been to the city too many times to count, but yeah...)
as for shopping? Times Square, Rockefeller Center, and South Street Seaport have awesome shopping. South Street Seaport is kinda by the Brooklyn Bridge and not very far from Ground Zero as well.
Dinner? The only places I know of are in Times Square. Tony DiNapoli's has some AMAZING Italian food, in a family style resturant (portions serve 2-4 people). John's Brick Oven Pizzeria has the best NYC pizza around. and there's always Hard Rock Cafe, Planet Hollywood, Friday's, Applebee's, Olive Garden, and basically every chain imaginable.
