Help with lunch suggestions
Assuming your $50pp is for food only, one of my favorites in the area is Bar Room at the Modern. Sleek, modern atmosphere, Alsatian small plates, right next to the Museum of Modern Art.
You may also wish to consider the newly revamped Monkey Bar if you can go a little bit over $50. Chef Damon Wise is formerly of Craft, the cocktails are done by Julie Reiner (Clover Club, Flatiron Lounge, Lani Kai), the wine by Belinda Chang (formerly of the Modern), and The Spotted Pig's Ken Friedman is a partner now.
