We were tipped off by Jan Eric Andersson that the McRib has arrived in South Korea. Provided was the following photo from what appears to be a release party there for the sandwich and related contest.
A peek at the South Korea McDonalds website confirms the availability.
Their YouTube clip showing their advertisement has the patty taking a rather odd fall from above.
It appears that they are running some type of contest with what they are calling the “Lucky Burger”. Having the McRib is lucky enough, adding a contest makes it a Very Lucky Burger. See their contest page here.
It appears they will be serving this McRib variant through January 29.
