McDonald's is real fast food restaurant that has made cameos and appearances in several anime and manga series.
McDonald's is the largest chain of hamburger fast food restaurants in the world. The company was founded in 1940 at San Bernardino, California (US) by the McDonald brothers and has restaurants in more than 100 countries, including Japan.
The appearances that the brand has made in the anime universe came in various shapes and forms, sometimes with no change in the logo and other times with some modifications that can go from just inverting the M (e.g. WcDonald's) to altering the whole name to make a clever or not so clever parody (e.g. Macross Nald's). In this page we include a list of these cameos and appearances, however if there is a location that might be based on McDonald's but has a corporate identity that clearly distinguishes it from the rest, then it would be better to create a separate page for it, specially if it's a main or very visited place in the series where it appears (e.g. MgRonald).
