Be careful what you wish for. For example, if you wander into Downtown Cocktail Room looking for a “one and done,” make sure it’s not the insidious layered shooter Finish Him ($12). Like the name implies, this blend of equal parts green Chartreuse (110 proof) louched Kübler absinthe (106 proof) and Smith & Cross Navy Strength Jamaica Rum (114 proof), and garnished with Angostura aromatic bitters, will punch through your soul and turn out the lights. Under such influence you might do something regrettable—say, make a cape out of a giant trash bag and run around Downtown. Not that we’re speaking from experience. Because we totally made that up. 111 Las Vegas Blvd. South, DowntownCocktailRoom.com.
