Well, it's been a kind of go-to spot for us when the in-laws are in town, because it is close, cheap, kid-friendly and convenient. But not because it's terribly special. The food is standard diner fare, and IMHO the best choices are breakfasts. Nothing that you couldn't do just as well on your own at home, but didn't because you felt like having someone else make it for you, y'know?
The pies look really good, but their crusts are actually drier and flatter than frozen supermarket crusts. Yuck. I actually would rather give the place 2 stars, except that we've always had decent service and the diner is clean, spacious and well-lit. So they squeak one more in. That and kids eat free on Tuesdays. And the pot of strong coffee they set in front of you. That also makes up for something.
Go for breakfast. Served all day. Hard to mess that up.
