Located along the old Boston Post Road since 1716, Longfellow’s Wayside Inn in Sudbury has served Thanksgiving dinner to generations of locals and travelers. This year, new executive chef Michael Brentana, overseeing his first Wayside Thanksgiving, and innkeeper John Cowden, in his fourth year at the helm, look to add a few modern twists to the classic spread. We caught up with Brentana, Cowden, and Guy LeBlanc, the inn’s director of marketing and museum services, to discuss their holiday plans.
