It can feel sometimes like every restaurant calling itself farm-to-table has a checklist of needs to both keep up with the current trends and make it feel authentic, like chalkboards, a barrel or two and drinks served out of mason jars. But for the Fagan family and Fagan’s Biscuit Barn on Peachtree Parkway, the food speaks for itself and farm-to-table is more of a family tradition than a popular trend. The Fagans are one of Forsyth County’s oldest families and cook classics, like chicken and dumplings, country-fried steak and gravy and, of course, biscuits, like grandma used to make.
