- Quarter Pounder with cheese
- Double Quarter Pounder with cheese
The second image is a grab from broccolicity.com website, where The McChronicles first heard of this interesting concept.
From what we're able to gather, if you're in Tokyo, head to Omotesando Shibuya East and you'll be close (there's a map on the website).
It also appears that some beverages are also available, as are fries, though they do not appear on the menu that is on the website (though they do appear in an image there). Another hint at that is the fact that the store sells the Quarter Pounder as a "set" meal. Makes sense.
There is more info available at the inventorspot blog.
