The beef patties are joined by thick-cut bacon, American cheese (one slice per patty), and special Stacker sauce on a toasted sesame seed bun.
Interesting, the original BK Stacker was a value-priced menu item while the King line are among the largest and most expensive burgers that the Burger King offers.
