There was a time when a few dollars could buy a surprisingly satisfying fast-food meal, and the 1980s helped make that experience unforgettable. Burger chains competed with discounted sandwiches, inexpensive sides, and increasingly attractive meal combinations. By the end of the decade, Wendy's had introduced a 99 cent menu that would influence the entire industry. Those prices look almost unbelievable today, although the dollars themselves were worth considerably more back then.
