Derek Brown's Columbia Room is an absolutely lovey place to visit regardless of your alcohol-drinking status.
In January, a new slate of no-proof cocktails will be released at Columbia Room. Currently, they also offer a tasting room experience of non-alcoholic cocktails as well.
From a recent feature from NPR:
Derek Brown is finding ways to cater to drinkers who don't want to drink. He's a Washington, D.C., bar owner, bartender and author of the book Spirits, Sugar, Water, Bitters: How the Cocktail Conquered the World.
At his Columbia Room bar in D.C., he says he's moving the "no-proof" cocktails from their own menu section to be alongside the boozy drinks in the main section.
