Denny's

The Denny’s restaurant chain gave away 1.7 million free breakfasts in eight hours, a new world record. They served their Grand Slam breakfast (two eggs, two pancakes, two sausages, two strips of bacon) at no charge between the hours of 6 a.m and 2 p.m.

The record was set on February 3, 2009. 1523 restaurants and over 36,000 employees across the United States were involved in making it happen.
