Artisan distillery Sipsmith have taken over the grand hotel's Palm Court, an area usually associated with afternoon teas, to make it into a heady, boozy gin den on Thursday, Friday and Saturday evenings.
Aptly named the 'Gin Palace', the bar is celebrating the history of this quintessentially British beverage through it's specially designed cocktails by Sipsmith Master Distiller, Jared Brown, and The Langham Head Mixologist Alex Kratena.
Each drink represents a different stage in gin evolution from 1690 when it was first born, to the introduction of the G&T in 1793 (good times) and then the arrival of molecular mixology in the 21st century.
Chose between delicious gin, ginger and lily from 1798 or take it back a few years with the 1689 concoction of gin, lemon and lime juice, syrup and champagne. Both excellent years for gin.
With accompanying tasting dishes on offer for each cocktail, live jazz to set the tone and fun details like some of the drinks being served in tea cups - it's an opulent night out.
Learning is fun.
Gin Palace is at The Langham, Portland Place, London, W1B 1JA until 24 November
