Yup. People often try to proscribe that it can only be done a certian way, but people like what they like. I like a Chicago Dog as much as anyone, but I also like other toppings too, inculding ketchup. I also like Chicago pizza AND NEw York pizza - it's not an either or.
I do die a little inside when people at the casino buffet ask they guy carving prime rib to throw it on the grill and make it well done. I mean, that's fine of course, but at that point it isn't prime rib so much as roast beef (which they also have). I once shared a knowing glance with a poor chef because I knew it was hurting his soul.
