The Arch Deluxe was a hamburger sold by the international fast food restaurant chain McDonald's in 1996 and marketed specifically to adults. Despite having the largest advertising and promotional budget in fast food history at the time,[4] it was soon discontinued after failing to become popular. It is considered one of the most expensive product flops of all time.[5]
