From the beginning, Insta-Burger King's menu focused on chargrilled, rather than fried, burger patties, resulting in a smoky flavour. Things were a bit simpler in the early 1950s, though, with the menu consisting just of hamburgers, cheeseburgers, coffee and fruit pies – and nothing was priced higher than 18 cents. Around 70 years on, Burger King's flame-grilled patties remain its USP, even if the prices have changed a little.
