Four Seasons Restaurant NYC

I've eaten there several times. First, it's in the Segram building, but not on top, and I believe the restaurant was designed by Philip Johnson, who designed the building with van der Rohe. The food is very good, but I doubt it would make any top 20 lists for restaurants in NYC. The food is straightforward, classic dishes with simple presentations. It is fantastically expensive, look to pay $40+ for entrees. The rooms are beautiful, particularly if you appreciate architecture. If your primary interest is seeing the room and having a good meal, by all means go. If your goal is to have the best meal possible, there are dozens of other places to consider.
