Burger King Japan offers all-you-can-eat Whoppers

TOKYO, Oct. 31 (UPI) -- Burger King Japan announced its annual all-you-can-eat Whopper promotion is returning for customers who purchase an $11 meal.

The restaurant chain announced customers at select locations will be able to order a challenge set meal Nov. 4-13 for $11 and those who finish the meals -- which consist of two Whoppers and a medium fries -- will be treated to as many free Whoppers as they can eat for 30 minutes.

The annual promotion, which began in 2010, has become known as "B"IKING, a play on Japanese buffets' use of the word "Viking" to describe the all-you-can-eat model.

Burger King Japan said locations are selling "advance tickets" for challenge set meals priced at just over $10, saving diners nearly $1.
