Around Radio City, Villagio on the Park On Central Park South - Best wait service I've ever had, cheesy crystal decor, good food, view of the park. Not cheap.
Upper West Side - Joanne's Trattoria on W 68th off the Park- small good spot for an inexpensive lunch, excellent meatballs, owned by Lady Gaga's parents. Not really revelant, but it explains the some of the wall photos and the t shirt stand. Nice quiet place.
In Times Square with the in-laws from flyover country - Carmines. Family style, huge portions, a bit of a circus that is too loud for me if not with the fam.
Little Italy - Forlini's on Baxter Street traditional red sauce Italian and you'd swear that guy sitting at the corner table is a mafioso. Food is very good if you like traditional Italian.
Anywhere else, Yelp has done me pretty good if you know how to use it.
