Grungy, greasy, full of angry polish men at all hours of the day and night, and standard food. But that's what makes the glider so perfect. The one thing worth getting is the porchetta (porketta)
There are four sections for seating - two rooms in the back are hidden if you come in the front (though there is a back entrance, too!) seat yourself, when there's a lunch rush, the place gets packed.
Classic American train car diner. I ordered the porketta plate with fries and pickledbeets and I felt like I was in the south. Good meal and quick service.
