How the heck do you rate a diner? If you walk in with diner expectations - which is to say, a big menu, decent but not exceptional hot food, open turkey sandwiches and cheap eats, this is four stars. If you are such a snobby foodie that hey, you can't appreciate anything unless it has balsamic vinaigrette and truffle shavings, then this is not going to be your cup of tea.
But if it's late at night or it's New Year's Eve and you have a yen for a roast beef sandwich, this is the place.
