Although its popularity has reached all corners of the world, at this time, no McDonald's restaurant serves the Szechuan sauce. Thousands of fans have petitioned to have the sweet-and-sour sauce back, but up until now, McDonald's representatives have chosen not to re-add this item on the menu. This particular sauce was introduced by the fast-food chain after a collaboration on an animated film, Mulan, with Walt Disney in the year 1998. The Mulan-themed Happy Meals were shortly released as a part of this partnership. When it came out that this sauce is actually an imitation of the red sauce that is served in Chinese restaurants, it was removed from the menu. For over 76 years, McDonald's has managed to hold a top place in the hearts of people all around the world. They continued to register some amazing growths year after year, even though they have been criticized extensively for serving unhealthy meals.
