McDonald's sucks; Burger King's burgers are so much better, but more expensive. In any case, junk food is shit, even though KFC isn't bad once in a while, and Subway (Which I don't consider to be junk food) is pretty good (Tuna Melt and Meatball Marinara).
I, myself, prefer an all you can eat sushi and sashimi buffet for $13 anytime
