Every once in a while fast food places will surpise you with something really good. I remember a year or so ago when McDonalds --the king of bad fast food (*) --came out with a flatbread wrap with warm grilled chicken and cheese (and a few other things) that was just delicious. Of course, it was too good tasting to stay on the menu.
