From Sumiao Hunan Kitchen in Boston!  Noted by Boston Bar Hopper:

Sumiao’s rendering of a Sidecar combines baijiu with cognac, Cointreau, and a lemon reduction. It’s a spirit-forward drink, and I was expecting a big blast of baijiu. But it’s a sippable, surprisingly smooth cocktail, and one that helped me get better acclimated to the fiery spirit.
