The LP (Little People--that would be us) enter through the side doors on 50th Street. The line is huge but moves fairly quickly. Carry as little as possible if anything.
And a camera makes you look like trash (he wrote cavalierly).
Restaurants? Its New York, for God's sakes. Trattoria del Arte at 57th and 7th is fine.
I'd worry more about rain than food. You can always scarf down a hot dog and a Coke from a street cart and carry a few Snickers in your pockets.
Have fun.
