CHRISTIANSBURG, Va. At Due South BBQ, We like to rub our butts, says owner, Marie March. March has seen the impact this BBQ joint has had on the New River Valley since day one. Campbell tells us, We dry rub it with our chicken rub, smoke it and then fry it back up to temperature. This New River Valley staple was already doing delivery, so they were able to pick right back up. Due South is open every day of the week, with a number of rubs and sauces to choose from.
