It's funny, I was preparing to say this exactly. I'm from the heart of Philadelphia and whenever I've had a cheesesteak in my travels, they just aren't like the "originals" back home. Does that mean it doesn't taste great to others? Not at all, it just doesn't taste that great to this Philadelphian. Keep in mind though, us Philadelphians can't even decide on who makes the best cheesesteak in our city! If I am not impressed with something, I won't sugarcoat it but I also do always try to encourage people to try something before they make up their mind, and don't take my opinion for gospel. I just won't lie and say "yep that Disney cheesesteak is great!" when in my seasoned cheesesteak opinion, it isn't.
I also feel this way about almost every morsel of Italian in Disney too, as where I live is heavily, heavily old school Italian. I will be honest when I say "yes, that spaghetti really isn't that great" (I'm looking at you, Tony's...) but I also would never think to tell others they wouldn't/shouldn't like it, etc.
