NYC Restaurant Recommends?

In a few weeks, my brother and I are going to NYC to see the new musical production of Young Frankenstein on Broadway. This is in honor of his 40th birthday (He liked that I had seen a show for my 40th and wanted to do something similar). We are seeing a Sat matinee and I'd like to take him to a nice restaurant for dinner after the show. He's not too adventuresome when it comes to food, so I suspect that a nice American, Italian, or Chinese style place would be just fine for him. Does anyone have any restaurant recommends for a place we can walk to from the Theatre District?
