With a La Marzocco coffee machine as its focal point, this café (just next to the Ballroom at The Dorchester) wears its heart on its sleeve and it’s no doubt that the baristas make some of the finest coffee in London. Beans come from south London roasters Alchemy, caffeine fanatics making a selection of brews that are really worth exploring. Of course, there are plenty of tempting treats to go with it, from pastries and fruit in the morning to salads and sandwiches until 10pm, as well an enticing display of cookies, cupcakes and homemade fudge, to go or to stay.
