My wife and I will be in NYC for one night in less than two weeks (Sept. 16th). We figure that a nice lunch out will be more cost effective than a nice dinner (correct?). We are staying in Midtown and would ideally like to eat around there. Does anyone have a good suggestion for a nice prix fixe lunch that is open on Saturdays? Unfortunately we don't have much time to get a reservation, so that may be an issue, but any suggestions would be greatly appreciated. Thanks.
