In 1977, Ron and Denise DeNunzio launched the opening of DeNunzio's Pizza Villa on Lowry Avenue in Jeannette. In the next few years, the couple established DeNunzio's Italian Restaurant at the same location and added three additional rooms to accommodate patrons. The glass room is quaint, yet elegant, and the golf room pays homage to many local golfers including their twin sons, Ronald and David.

20 years later, in 1997, and in the same week that their third son was born, Michael, the Monroeville location opened its doors. In 2017, an additional dining room, seating up to 65 guests was annexed, and the wrap around bar was expanded to create additional seating for 25 patrons.

In 2004, The Italian Chop House had its grand opening at the Arnold Palmer Airport. Guests can enjoy a cocktail on the terrace by the runway while watching the beautiful sunsets, have dinner under the crystal chandeliers, or listen to the sounds of music at the Sinatra Bar.
