subway I love their food, There are alot of USA fastfood resturant here I dislike all :/ except subway, since it's really unhealthy (something I realized after watching super size me or whatever the name was).
That film is pretty misleading though. Even if you eat McDonald's all the time, you could actualy stay healthy. Work out, or just walk regularly, don't eat too much food (which the guy in that film always did, and supersized every time they asked him) and don't eat the more unhealthy foods on the menus.
Anyway, I love McDonald's fries, which kind of sucks, because I'm a vegetarian and I remember there was a big lawsuit over the fact that McDonald's uses pig fat to cook their fries. Maybe they changed their method because of the lawsuit, though. Don't know.
edit - oh, and also, McShakes for the win. I love them. Last time I was at the mall, all I bought was a large milkshake from Mickey's.
