Since it was Christmas and I had cranberry juice, I added a shot and a dash of orange bitters - Christmas Mule! (alternatively, as it's a cross between a Moscow Mule and a Cosmopolitan, Cos-Play Mule!}
There is a restaurant nearby which serves a version with Sake, blackberry and malbec reduction, and ginger syrup. Tastes great! They call it Tokyo Mule.
