I don't think that means much. I have eaten at Pizza Hut twice in my life and the only thing that "impressed" me was the other time when I ordered a small sized pizza (I don't remember their exact terminology anymore) and they brought me a bigger one by accident. I naturally only paid what I'd have paid for the smaller size. The pizzas themselves were nothing to write home about.
The reason why Pizza Hut has a positive ring in my ears is solely due to Code Geass and C.C...
