Handily placed for your visit to your doctor in Harley Street or, perhaps more likely, the BBC Radio Theatre, this is one of Marylebone’s two remaining mews pubs, this one built in 1777 and grade II listed. The etched glass windows still with the Dover Castle name show the original layout and purpose of the two front bars before the removal of the partitioning. Note the mirrors underneath the dividing beam which allowed coachmen to observe when their passengers were ready to depart. For many years a Sam Smith's outlet, this has been taken over by Bloomsbury Leisure, the operators of the Euston Tap, and now has up to four real ales plus around twelve keg beers. The dark-wood Sam Smith's interior has given way to a lighter feel, with two front-bar areas and two snugs in the rear, with some comfortable banquette seating but also some high counter-tables and bar stools for traditionalists. Downstairs, London's first Xiao Mian noodle kitchen has opened, specialising in ramen dishes; if you do not want to sit downstairs the staff will bring food up for you. A jackalope is a cross between a jackrabbit and an antelope, a mythical creature of North American folklore. Note the jackalope wallpaper and pub swingsign; but what the connection is with the upmarket Harley Street medical area, we do not know!
