This topic comes up every two years or so. As I said last time, I've eaten at some pretty damned fine establishments (Russian Tea Room, Citronelle, La Cote Basque, Tavern on the Green, Restaurant Eve, and -recently- Inn at Little Washington and Restaurant Eve).
For what you pay, I think the Great American Restaurants are a good deal. The food is somewhat creative, and the service is attentive.
