Burger King premium burgers
As far back as the 1970s, international fast food restaurant chain Burger King has attempted to introduce a premium line of burgers. These sandwiches are part of a system which eventually became known as the barbell strategy; a plan designed to expand Burger King's menu with both more sophisticated, adult-oriented fare along with products that are more value-oriented.
