“The intangibles that enabled me to achieve my greatness also contained the seeds to my destruction.” – Joseph Costanzo, Jr.

The behind-the-scenes true story of Pittsburgh area restaurateur Joseph Costanzo, Jr., is a study in contradictions. A complex character, Costanzo was at once confident yet unaware; generous yet egotistical; and meticulous yet careless.

The son of Italian immigrants, Costanzo turned the blue collar burb of McKees Rocks, Pennsylvania, into a sought-out destination for fine Italian dining at The Primadonna, which in its heyday drew the attention of celebrities, sports icons and well-known journalists — and eventually the federal government.

Known for its signature Southern Italian dishes that nourished stomachs and souls, The Primadonna’s generous portion sizes were eclipsed only by Costanzo’s larger-than-life personality, explains his daughter Maria C. Palmer.

“The moment that you walked in, regardless of how busy we were, my dad was at the front of the house, and he was greeting you,” Palmer recalled during a recent interview. “My dad was invested in customers. He wanted to be part of people’s lives. I think that’s what makes this experience so memorable. People loved being special.”

In her new book, On the Rocks, Palmer and co-author Ruthie Robbins, who was Palmer’s high school English teacher, open a door to the past and welcome readers to The Primadonna, where Costanzo treated neighborhood regulars with the same warmth and hospitality with which he greeted the likes of Danny Aiello, Jamie Lee Curtis and Tommy Lasorda.

Written from Costanzo’s perspective, On the Rocks traces his unlikely rise from a postal worker with an impossible dream to owner of a nationally acclaimed restaurant. Along the way, On the Rocks serves up quirky characters, entertaining stories, delectable dishes, celebrity sightings, great memories and enduring friendships.

A classic example of blind ambition, Costanzo is at once the driving force behind his success and the cause of his own downfall. And as the story unfolds, readers follow Costanzo from the day-to-day frenzy of a hot-spot restaurant to life behind bars.

“The restaurant was like his third child; it was the son he never had,” Palmer reflected. “He was at the top of his game when everything spiraled out of control. That’s what makes this story so rich. He really did the impossible. He took this nothing, failing business and turned it into this diamond in the rough. Then it all got pulled away. Just as fast as it rose, it fell.”
