There is a nice family restaurant serving breakfast and lunch in nearby Norge, VA,  (https://www.honeybutterskitchen.com).  It is about a 20 minute ride.  The neighboring town of Toano offers a unique breakfast and lunch experience at Hohl’s (https://hohlco.com/). Otherwise, Williamsburg and Richmond offer a very wide selection of eateries.

Gauthier Vineyard periodically offers wine pairing dinners and other culinary events in the winery’s tasting room.  You might want to schedule your group stay around one of those events.  Check the event calendar on the Gauthier Vineyard website for the dates, times and menu selections.
