At a time when punters are tiring of the speakeasy’s secret-doors-and-passwords song-and-dance routine, Happiness Forgets manages to pull from the best of the trend (a discreet location, a cosy space, low lighting and classic cocktails) with none of the artifice. It may well be a candidate for The Perfect London Cocktail Bar. Service is warm, personal, wry, and deeply inviting. Drinks range from classics to house cocktails, though you can also confide what you’re in the mood for to get something bespoke shaken up. A stream of guest bartenders whose home bases are as far-flung as Stockholm and Frankfurt regularly stop in to mix up something special. Just bear in mind: while reservations aren’t required for entry, Happiness Forgets’ popularity means snagging a walk-in seat isn’t a guarantee.
