you wanna do the open top bus tours fella, best way to see a lot of it, and its hop on hop off if you see something you wanna have a longer look around, you wanna try the fulton fish market, its early, like 4-5am, but what a site to see!!
to ne fair, the pizza is good everywhere, proper new york style pizza, proper nice! and you can't not have a hot dog whilst your there!!
i loved macy's, and was surprisingly cheap for shopping too
but as already mentioned, your better doing plenty of walking, as you'll see so much more, and get an extra big memory card for you camera, cos you'll never run out of things to take pics of!
you could try get a knicks game in at madison square garden or a yankee game???
enjoy it whatever pal, and you'll want to return again and again
