Once an air raid shelter, this underground hideout will transport you to 1940s London for some drinking on the ration. Follow the "to the train signs, chat up the ticket inspector and step foot inside the old tube carriage complete with vintage TfL carriage seats, white underground tiles and "Mind the Gap" notices.

Check out the menu, printed out on an old newspaper no less, and choose one of the many ration-inspired cocktails garnished with peardrops and crumbled Oxo cubes, served up in teacups, thermos flasks, and milk bottles. So retro. The attention to detail here is insane, so lose some hours to checking out the decks, hiding in the air raid shelter and drinking on the tube (again). No need to top up your Oyster, just your drink.
