Passover friendly NYC
This isn't the best place to ask about non-Kosher 'Passover menu' options; you might want to try the general NYC board for that.
For Kosher restaurants that will be open on Passover (some for Seders, some only during chol hamoed, M-Th next week), see this thread: http://chowhound.chow.com/topics/838640
You're in Manhattan. There are great Kosher restaurants that stay open on Pesach. why not just go to one of them? Like the new tapas place, here's their passover menu: http://ladinogrill.com/passover.html
koshertopia.com has a pretty good list
Many , most?, Manhattan restaurants are online. So you should be able to check out restaurants and find ones that meet whatever limits you choose to set.
Depends what you mean by friendly and how non-kosher you would go. Steak and potatoes is "passover friendly", as are most roast chicken recipes. In fact, lobster is "passover friendly" in that it contains no chametz, although it is clearly super-non kosher.
Without knowing what your standards are, all we can offer are certified kosher options. Also, as others have said, if you want non-kosher options your best bet is the general NY board.
