You can't get any more American. It was Invented in the city of Philadelphia. And its a gastric statement. Basically its a sandwich containing thin-sliced sauteed beef, melted cheese, and sauteed onions, served in a long Italian roll. But its more than that. It is a boastful statement of amazing food. It is fit for both kings and gangsters and yet simple enough for the common man. It is a piece of heaven. Its a work of art. It is an overdose to your culinary senses. It requires you to use both your hands; it requires you to put etiquette dining to the side and it is just pure friendship, merriment and raucous laughter. It demands big bites. It's best enjoyed in groups and at events and/or just when you know you damn well deserve it! A single person eating it alone may often hum, laugh to himself and even talk out loud like a crazy nut - It's that good! That is why this sandwich is called the King of Sandwiches!
