When ordering a cheesesteak, the idea is to let the cashier know a.) that you would like a cheesesteak, b.) what type of cheese you want (American, Provolone or Cheez Wiz), and c.) whether or not you want fried onions. And you have to be as concise as possible while doing so.
Locals have become so adept at this practice that they basically have it down to three words: saying “one wiz with” to the person behind the counter means that you would like one cheesesteak [denoted by the “one”] with Cheez Wiz as your choice of cheese [denoted by the “wiz”] and with fried onions [denoted by the “with”]. Similarly, saying “one provolone without” would secure you a single cheesesteak [one] made with provolone cheese [provolone] and without fried onions [without]. And saying "three American with" will get you three cheesesteaks, each with American cheese and fried onions.Ok. Got it? Now go ahead and test out your ordering prowess for real.
