The 12th Brick Grille is a bar/sandwich shop which is literally within the walls of the military prison. The 12th Brick gets its name from the fact the US Military Prison used to have a brick factory on the premises, with military convicts providing the labor. Every 12th brick was stamped "USMP"... thus the name. They serve great beer there, too. I had a Boulevard Pale Ale and SN1 had a Boulevard Wheat.
