Thank you all for your help, here is where I went and what I thought:
Friday evening: Arrived late at the Hilton Mid-town, wanted something close to hotel and within walking distance; walked to the Parker Meridien, found the Burger Joint behind the curtain, probably about a 15 minute wait at around 8 pm. Ordered 2 Cheeseburgers and 2 fries; cheeseburgers were cooked perfectly and were very good, almost tasted as if hand formed; fries were very good, not sure if they were fresh or frozen, similar but better than McDonalds fries. Not cheap by my standards but probably cheap by Manhattan standards (cheeseburger: $7, fries $3).
Saturday: Dinner at Crispo. Very good and again, probably very reasonably priced by Manhattan standards; four of us split the Calamari and Zucchini Friti appetizer and an order of Risotto balls; both were very good; for an Entree, I got a "special" of Pappardelle with wild mushrooms, very good again, with what appeared to be homemade pasta. Very much enjoyed our meal here. Service was very good by both waiter and bartender (did not get his name but had drinks while we waited at bar).
Sunday: spent about 4 hours walking around Chinatown, Lower East Side, Soho and Greenwich Village; I had no idea where to go in Chinatown but wanted to taste some Dim Sum; asked someone on the street and ended up with take-out from Oriental Food Restaurant at 103-105 Mott Street; ordered steamed pork buns, shu mai, har gau and beef meatballs; very cheap ($8.80) and very good but not outstanding; of note was that restaurant was very crowded and I didn't see 1 Caucasion, usually a good sign and it was; walked over to LES and found Katz's Deli, placed my order for a Pastrami on Rye to go, did not eat it until around 11 pm (after our 4 hour car ride) so it wasn't "Hot" Pastrami but it was delicious nonetheless, handcut, thick, tender and great taste!
