Rarely have time to cook several items on a regular evening, so often pick up a small side and concentrate on the main dish. Which grocery store or prepared foods store has the best mash? Like it freshly made, of course, and with a few lumps.
Agata & V
Marche Madison and Whole Foods -- theirs are fine, but not lumpy
Dean & Deluca
A few of the other prepared foods places on Madison in the 80's....?
Or, maybe a reasonably priced restaurant, such as Candle Cafe, Vivolo, etc (never had them there).
