The first starts this Saturday, November 17 and runs through November 21, from 2pm to 11pm. According to RocketNews24, the deal is any customer who orders and finishes a Kuro ("black") Burger combo meal for 880 yen (~$10.83 US) will have 30 minutes to down as many Whoppers, fries, onion rings, and/or Cokes as he/she likes for no additional charge.
It must be noted that the 30 minutes starts running when you purchase the combo.
The second segment runs November 22 through November 30, and offers the same, but with the purchase of any one of four Whopper combos with prices ranging from 880 yen to 1,110 yen ($10.83 to $13.67 US).
The logistics of how the deal works is as follows:
1. Order designated combo and receive a receipt with a time stamp.
2. Finish said combo and bring back the burger wrapper, empty cup, and paper bag to the register and receive a special buffet card.
3. Use buffet card and receipt to get Whoppers, fries, onion rings, and/or Cokes until the allotted 30-minute time limit runs out.
The 30 minute time limit makes it more of a competitive eating challenge rather than an enjoyable buffet. I don't think I could comfortably finish the combo in 30 minutes let alone eat more afterwards.
