KFC definitely. The chicken is dry and so are the chips, McDonald's chips are nicer. Also KFC is expensive compared to McDonalds ;S
In response to the other answers, I'm not even that keen on bacon. It's just the fat I can't stand. Even cutting all of it off there's always more of it lurking somewhere *shivers*. I love nutella though, always have. Oreos are good but not that special.
