On the Rocks Serves Readers a Taste of Iconic Italian Restaurant, Reveals Family Drama

In the 1980s, Joseph Costanzo Jr. created a destination restaurant in the declining neighborhood of McKees Rocks, Pennsylvania, without the benefit of social media, cell phones, viral videos or Yelp reviews. How? Through good old-fashioned handshakes, phone calls and Costanzo’s larger-than-life personality, says his oldest daughter, Maria C. Palmer.

“Word-of-mouth was the restaurant’s greatest marketing tool and remains the most authentic proof of the exceptionality of the restaurant,” Palmer writes in the new book, On the Rocks.

That restaurant was The Primadonna, and it attracted the likes of Danny Aiello, Jamie Lee Curtis, Pat Sajak, Michael Keaton, Tommy Lasorda and many other celebrities.

“We estimate that over the 18 years that he was in business that a little over a million customers came through our door,” Palmer said. “His character really helped to build the empire that the restaurant became.”

Written from Costanzo’s perspective, On the Rocks, by Palmer and co-author Ruthie Robbins, dishes up heaping helpings of nostalgia, with entertaining stories of quirky characters, delectable dishes, great memories and enduring friendships from a time when dining out was an experience to savor.

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 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.

On the Rocks traces Costanzo’s unlikely rise from a postal worker with an impossible dream to owner of a nationally acclaimed restaurant, where the often 2-hour wait times only served to brew deeper connections, adding to the familial appeal of a community hotspot united by Costanzo’s drive to turn the blue collar burb of McKees Rocks, Pennsylvania, into a sought-out destination for fine Italian dining.

But Costanzo’s dream comes at a cost, and as the story unfolds, readers follow him from the day-to-day frenzy of a wildly popular restaurant, through a failed attempt to run for public office, 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.”
