This 12- to 14-ounce tenderloin, featured in Gourmet magazine, is a 1-inch slice of pork loin cut fresh each morning, butterflied and served at a golden brown. More than double the size of the generous bun, it even spills over the plate. Diners eat at long tables in the back, next to the motorcycle parts and candy bars. While Larry Bird and Sam Alford were spotted here recently, waitresses were more impressed by a construction worker who finished two. ($6.50)
