Workers can be seen at Old Country Buffet, Whitehall Mall, where the all-you-can-eat restaurant closed on Monday for an extensive makeover. A restaurant spokesperson said the interior renovations will include everything from walls to flooring. New islands will feature the same menu with a few new items. Old Country Buffet, which seats 400 people, has been a fixture at the Whitehall Mall property for 18 years. It will reopen Oct. 5.
