I am a fan of pretty much every sandwich posted here so far, but I have to list one that most people aren't aware of. The "Fat Cat' or "Fat Sandwich" as it evolved into many forms. The come from the notorious Rutgers University Grease trucks that have fed countless drunk college students at 3AM. (me being one of them. lol) They are open for lunch and dinner too, but the Fat Cat was usually reserved for late night debauchery. The Original Fat Cat: Basically two burger patties on a sub roll with ketchup, mayo, lettuce, onion, tomato, and French Fries! However, over the years it has morphed into the behemoth that now exists.
