Cheesesteak is a sandwich consisting of meat and cheese that originated in Philadelphia.
Tony Cicci once ordered a cheesesteak in Vic's Las Vegas Lounge. He was not impressed with the sandwich provided, and told the waiter "now I want a cheesesteak and I don't care if you gotta fly to Philadelphia to get me one". (DS9: "Badda-Bing, Badda-Bang")
