The Arch Deluxe was the McDonald's sandwich marketed as having a “grown-up taste” when it launched in 1996.
McDonald's positioned the Arch Deluxe as a more sophisticated hamburger for adults. Its advertising emphasized a specially developed sauce and ingredients intended to distinguish it from the chain's standard burgers. The campaign was unusually elaborate and expensive for McDonald's at the time.
The product became one of the company's best-known marketing failures because sales did not meet expectations. The experience showed that a strong advertising campaign and a deliberately adult-oriented identity could not guarantee that customers would adopt a new menu item.
The Arch Deluxe is sometimes confused with the Big N' Tasty, another McDonald's hamburger introduced in the 1990s. The Big N' Tasty had a different recipe and was not the sandwich associated with the “grown-up taste” campaign.
