TOD: Skip makes the VERY best gourmet mac-and-cheese. He bases it on a recipe from the book TWENTY by Michael Ruhlman. It uses a Soubise sauce, for those who follow cooking terms.
(As far as restaurants' mac-and-cheese, Schnipper's on 8th and 41st is quite good, especially when you mix it with some of their Sloppy Joe, which you can with a dish they call "Mac & Joe.")
