New Whistle Pig proudly carries the torch lit by its predecessor, the original Whistle Pig, and together, the two establishments have been a Niagara Falls staple since 1939. The restaurant's modern incarnation harkens back to old-fashioned American diners of the 1950s and '60s, right down to its homemade milk shakes and glass-bottled soda. The menu also conjures simpler times with its straightforward, no frills cheeseburgers and fresh-cut fries, which stand in contrast to the more complicated "The Whistle Pig," a skinless hot dog wrapped in bacon and smothered in cheese sauce. Throwback themes are especially evident on Friday nights, when classic-car owners park outside and compare all the weird places their vintage vehicles are starting to grow hair.
