Ritters is, for me, the definition of a diner. If you go early an old grandmother will serve up a sloppy egg breakfast on plates that you can't be sure if they've been washed more than twice. Go late night and you can join drunk college kids and "the ladies of the evening", just be warned that someone may have painted a section of the restroom with a fine layer of regergitated food ("hey, is that creamed corn").
Say what you will about Ritters, it is a place full of character and full of characters. Not to be missed.
