McDonald's Cheeseburger is, for better or worse, really (with McDonald's
Hamburger) the original modern fast food burger made quickly in an assembly line process for a uniform, profitable product. The formula remains simple: a beef patty, American cheese, pickles, onions, ketchup, and mustard on a soft hamburger bun.
The price seems to vary quite a bit and fluctuates around $1 (I was quoted a price of
98 cents at my local McDonald's but they also offer two for $1.79 under normal menu pricing). In some markets, it actually costs
more than a McDouble (which only differs in that it contains an extra beef patty).
