The Arch Deluxe was a hamburger sold by the international fast food restaurant chain McDonald's in 1996 and marketed specifically to adults.

[5] The Arch Deluxe was a quarter pound of beef on a split-top potato flour sesame seed bun, topped with a circular piece of peppered bacon, leaf lettuce, tomato, American cheese, onions, ketchup, and Dijonnaise (a portmanteau of Dijon mustard and mayonnaise) sauce.

Rather than change its existing menu items or marketing strategy, the company decided to create a new line of sandwiches with what would hopefully be perceived as more sophisticated ingredients.

[citation needed] The Arch Deluxe was first tested as a "Taste of the Month" burger in October 1995 at McDonald's restaurants in Canada.

Customers were dissuaded, however, by the high price, which ranged from US$2.09 up to US$2.49 (equivalent to $5 in 2023),[7] and unconventional ads, and consumer groups were upset by the higher caloric content.
