Hot dog, fries, and canned soda for $15!!! but it's "historic" so they get away with the unmatched prices. Buy a salami for your boy in the army! I have no idea what it means but people seem to like it. They also do this very strange thing where they give you a tag when you enter and you use it to pay and get out otherwise they will make you pay $50.
