The Whisky Exchange, which opened online in 1999, offers one of the largest selections of whiskies in the world. At its giant Covent Garden bricks-and-mortar, whiskies, single malts, blends, bourbons, whiskies from around the world and aged Cognacs and Armagnacs fill the basement. You can also bottle your own directly from limited release casks. On the ground level are found all kinds of spirits and Champagnes, including small, artisanal produce. It hosts master class whisky tastings and can schedule private tastings for 8 to 24 on Monday and Tuesday evenings.
