This weekend is your last chance to visit Normandie Farm before chef/owner Cary Prokos ends his 39-year run. The Potomac landmark has been sold to a D.C. restaurant company with deep pockets and big plans for its next incarnation. (More on that in our May 5th edition.) Prokos says he’s been touched by all the good wishes from longtime customers, some of whom have been buying up his plates, coffee mugs and popover tins. “They’ve all been coming out here to say goodbye, but we’re the ones who should be saying thank you to the entire community for supporting us all these years,” he says. “Some days have been better than others, but it’s all been a fantastic adventure.” Prokos is throwing a party Sunday night, open to everyone at $30 a head, featuring a cocktail buffet with all the goodies that are still left in the refrigerator.
