(Twitter: @elitedaily)Because there is nothing more appealing than a slab of dark gray meat on a dark gray bun, McDonald’s Japan has followed Burger King’s lead and introduced a burger that doesn’t look like anything you’d really want to eat. McDonald’s “Halloween” burger is a limited-time offer that follows only weeks after BK Japan unveiled its black Kuro Burger to much Internet buzz. The McD’s offering is slightly more colorful than the BK competitor, since it uses good ol’ yellow cheese instead of the eerie jet-black slices.
