The Mamido burger, for instance, which sells for ¥390 ($3.25 at ¥120 to the dollar), is a highlight of the menu. The "bun" is actually a sponge cake, the "patty" inside is chocolate cream, and the "pickles" are kiwis. The deep-fried fish burger, meanwhile, priced at ¥440 ($3.70), features a banana shaped like a fish fillet in sponge cake. It is topped with "tartar sauce," which is actually fresh cream. And the gratin burger, also at ¥440, is a sandwich with a cream cheese and fruit filling.Link (Thanks, Olivia!)
The side dishes are equally ingenious. The French fries look like the real thing but are actually custard cream covered in starch powder and deep-fried. The fries, diners are told, are delectable when topped with ketchup. Without exception, every item on the menu is a sweet of some sort.
