I don't consider myself an expert on Coraopolis, because I'm on the other side of Pittsburgh. But I'll do what I can. Three recommendations fairly near to Coraopolis:
In Coraopolis itself, there's LoBello's Spaghetti House, an Italian place run for over 60 years by Rose LoBello. I've only eaten there once. To be honest, I wasn't blown away by the food - but I was blown away by the sheer love and enthusiasm Rose showed.

My preferred order for two people is a #2 sampler platter: a small haluski, four pierogies, and a piece of kielbasa. This will leave me and my wife full for $7.50.

I've eaten there twice; one visit was very good, and one was good but not exceptional. I'd call the menu "Continental"; it includes dishes that I haven't encountered elsewhere like escargot en croute and chicken Zurich.

It is much pricier than most Roadfood restaurants, but the food is delicious and elegant. And the building is splendid - the building was built in the 1930s by someone who really wanted a castle, and wasn't bothered by the fact that he was going to build his castle in western Pennsylvania.
When weather permits (which it should in July), the Hyeholde offers elegant picnics on the grounds with advance notice. I haven't yet tried the picnics, but it sounds very lovely.
