Rockefeller Center Food Court [30 Rockefeller Plaza]
The place to meet if you work on Park Avenue and your friend works on 6th Avenue. I'll always have a soft spot for Manchu WOK, mostly because they will call me "Young Man" until I am 50 (don't worry girls, they will call you "Young Lady" for just as long). And their combination plate is surprisingly a little above mediocre. The ubiquitous Hale and Hearty is predictably solid. I'm not sure what everyone sees in Cucina & Co., but it is there. Mendy's, Tossed, and Two Boots round out some other places that deserve consideration. Only one major problem: getting a table at lunch time can be a battle, but if you are vigilant and aggressive you should be ok.
