I was reading it as the midtown. I see First through Eighth Avenues running through. Seems too wide of an area to be downtown. The streets down there are very narrow. I could be wrong. I think downtown is much too hot for them to try again.
"Hot" is a bad word to use! Look at the fire all over the map and in usama's hand.
I am thinking just the tip of lower Manhattan, so the width is okay, not the entire lower Manhattan where it is wide than becomes narrow. Also, the way the streets or land parcels on the lower right go off in another direction more closely matches lower Manhattan.
