The White Castle Restaurant in O'Fallon is under construction.
Signs on the doors of the restaurant, located at 2212 Highway K, indicate the dining room is temporarily closed but the drive-thru remains open to customers.
According to O'Fallon Director of Planning and Development David Woods, the restaurant is doing renovations to the interior and exterior, including removing and replacing light fixtures, replacing awnings and adding a new sign.
O'Fallon White Castle District Manager Mary Troia said the renovations will most likely be complete by Thanksgiving. The White Castle dining room is estimated to re-open on Nov. 18.
