Want a burger to match your soul? Burger King Japan's black burgers may fit the bill.
The Kuro Burger—translation, "black burger"—and deluxe sibling the Kuro Diamond Burger don dark trimmings, including a black bun made from squid ink and bamboo charcoal, as well as black cheese infused with bamboo charcoal (or possibly from emo cows). Oh, and that dark, oozing substance? That's black onion, garlic and squid ink sauce.
To be fair, these burgers are back in black.
