Burger Shots
To compete with the iconic tiny slider-style burgers of White Castle, Burger King came up with their own monstrosities since the 1980s. After 2004, Burger Shots were sold in two-packs or six-packs, topped with mustard, ketchup, pickle, and placed between seedless buns. There was also a breakfast option with egg, cheese, and the choice of bacon, ham, or sausage. The Burger Shots was the third time the company tried another White Castle-style concept, and it wasn’t a charm, it failed miserably.
