Earliest White House floor plans by architect James Hoban label the southwest corner room on the first floor as a dining room, but it was used as an office, library and cabinet room before finally being used as a dining room.
This tiny cache is located on Northwich Road in the Whitehouse Industrial Estate, Runcorn. This location is not a dining room. You can get no food here, apart from Guinness, which is a kind of food.
