'PIG 'N WHISTLE' in Denver, Colorado. Eddie ‘Punch’ Bohn opened this Denver landmark in June of 1924. The restaurant served up the some of the best Bar-B-Que in the Western states and also had a comfortable motel for weary travelers. Sadly, after 65 yrs it was closed in 1991. THE PIG, as it was known, stood silent at 4801 W. Colfax until a fire destroyed it on April 22, 2010.
