Philadelphia Cheese Steaks

When I first arrived at college in Philadelphia many years ago, someone had to explain to me what a cheese steak was.  After 4 years of eating in the city of brotherly love, I learned that a cheese steak is a hot sandwich with cooked beef, cheese, and often onions and other condiments like ketchup and Cheez Whiz.  I dont know how to say this humbly, but I never thought Phillys favorite sandwich is as good as the version I now make myself (and my family, who has tried both versions, agrees).  Try it for yourself and let me know what you think! Have you ever tried a real Philadelphia Cheese Steak?
