Burger King Japan measures chicken sandwiches against diners' phones in weird promo

Burger King Japan is offering a Big Chicken Fillet, which it says in a weird promo is bigger than their diners' phones.

The chain's new Big Chicken Fillet and Big Chicken Filet Deluxe sandwiches have fried chicken fillets that weighed 185 grams each before frying.

The chicken fillet has a diameter of approximately 5.1 inches, which is big enough to stick out of the bun.

Burger King is so confident about their claim on the sandwich's size that they’re running a “Bigger Than Your Phone?” campaign at their flagship Shibuya Center-gai branch in downtown Tokyo.

Diners who believe that the Big Chicken Fillet is smaller than their phones could tell the staff they’d like to participate in the challenge and show their phones.

If their phones turn out to be larger than the sandwich, they’ll get a free coupon for another sandwich or set meal, which includes French fries and a drink.

A standard Big Chicken Filet sandwich costs 590 yen while a Big Chicken Filler Deluxe set carries a 990 yen tag price.
