Tatarian makes it a trio for Lenka Juchelkova and Mike Huggins, who also run Union Lodge No. 1 and the Arvada Tavern. This one’s dedicated to the high art of cocktails and the delicate balance of sour, sweet, boozy and bitter. The decor is posh penthouse; your drink might be smoked or bolstered by house bitters and tinctures. Tatarian, named for a type of shady maple that once graced every yard in the neighborhood, is the fanciest branch on the family tree.
