The Rose & Crown (The Snowmen)

 was a London inn run by Bob Chilcott in the late 19th century.

Clara Oswald worked as a barmaid there before assuming the name "Miss Montague" and becoming a governess. She returned briefly as a favour to Bob when he was short-handed in December 1892. It was in front of the Rose & Crown's door that Clara met the Eleventh Doctor on the night of 23 December 1892, and the pair inspected one of the Great Intelligence's snowmen. (TV: The Snowmen)

The name of the bar may be a reference to previous companions Rose Tyler and Donna Temple-Noble.
