"Restaurant chains have left an undeniable imprint on American culture. Without them, where would we feed during endless drives across desolate highways? How would Tarantino have introduced us to Jules and Vincent? Who would sponsor our professional sports stadiums?
Not all chains are created equal, though. Some, like the 14 we honor below, have been true game-changers -- not because they slapped their name on a college football bowl game, but because they greatly influenced the way Americans and (sometimes) the world eats."
