Brought to life by Belvedere and Mr Black's Coffee Liqueur, the rather daring menu features everything from java and vodka combos to orange chocolate mash-ups. Sounds revolting, but we're told they're actually really nice.
As it's Christmas, a special chestnut martini made with some extremely velvety Crème de Chataigne will also be served.
We know it's still too early, but Merry Christmas.
The Belvedere Espresso Martini Lounge is at Gaucho Broadgate, 5 Finsbury Avenue, EC2M 2PG until December 23, 2017
