Really depends if you are looking for cheap eats, but my one recommendation would be Normas - it is amazing!! It is not a $3 breakfast and is served by 'proper' waiters, but is great.
I've been 3 times now and am still as in love with it. The portions are HUGE, if you get a waffle with berries, the pile of berries must be about 3-4 inches high!! Noone ever finishes their portion and you can ask to take it away if you want! Not unusual in the US i believe, due to oversized portions!
It's only 5 blocks from your hotel (on 57th between 5th & 6th)
