This isn't the first time the fast-food chain has released a four-patty burger. In November, Burger King launched a $4 that contained more than one pound of beef - and no bread.

That same month, it also started selling an $4 in Japan, which Burger King said tastes better than it looks. Its distinctive look comes from its four-cheese bun.

And in October, it launched a chocolate-and-maple-syrup $4 in Singapore, after noticing diners dunking fries in their ice-cream.

Burger King kicked off 2021 with a $4, unveiling its first new logo in 20 years.

It has also announced plans to $4 with lockers for collecting orders, three-lane drive-thrus, and conveyor belts that can deliver Whoppers to your car.
