Dram & Grain underground whiskey den in Adams Morgan "If you want to nab a coveted seat in this underground whiskey den, you’ll have to text the bartenders on a burner phone. The number? That’s a secret. Those in possession of the number can choose from 15 signature drinks including a cold-smoked cocktail and an elixir that morphs from a Sazerac into a Vieux Carre by way of a melting ice cube made of Benedictine, vermouth, and bitters. For now, they’re only open Saturday nights."
