The decor is less vintage and more just hasn't been cleaned or changed in a few decades. The portions were smaller than you'd expect, which my girlfriend suggested might be a harken back to the day. Problem is the prices aren't proportionate.
My pastrami and Swiss on marble rye was pretty burnt and fairly bland. The potato salad hardly had any flavor.
I thought perhaps my taste buds were off except the root Beer float was pretty tasty.
Watching a waitress pickup spilled food off the floor with her bare hands, throw it away, then turn around and serve two plates to other customers did it for me.
The ice cream was good, but other places know how to scoop from a carton too...
