The iconic McDonald's Big Mac has a Pittsburgh history. The story goes that Uniontown native Jim Delligatti, an early McDonald’s franchisee, wanted to boost sales at his dozen restaurants. In 1967, he introduced the Big Mac at his Uniontown restaurant for 45 cents — more than twice the price of a regular hamburger at the time — and sales increased by 12% within a few months. In 1968, McDonald’s rolled out the new sandwich nationwide. Delligatti’s son, Mike, demonstrated how a Big Mac was made. R
