Burger King has another interesting promotion, all-you-can-eat, called BiKing. The name is cute because it is a play on words. All-you-can-eat or smorgasbord is called Viking or "baikingu" in Japanese and sounds quite a bit like BiKing.
The promotion runs until the end of the month and works like this, you order a large side of one of the featured sets. Eat it all and you can have more within a 30 minute time span. Pretty restrictive, considering you have to resent an empty tray, cup and the receipt to receive more.
I suppose young people might consider it a challenge, but eating as much as you possibly can of this type food as possible in a short amount of time cannot be a good idea. Interesting, but I like the previous promotions much better. The black burger looked pretty cool and was actually pretty good.
