125 Chancery Lane, WC2

It is an Argentinian cantina now, serving steak and vino rosso lunches to solicitor's clerks, but 125 Chancery Lane was built as a pub.
Because it was a Victorian pub the clues are all there, sculpted in stucco on the facade. Look at the great big bunches of grapes spewing out of the urns, and the vines running along under the architrave.
Even the pub's name is there in 3D - the Mitre. In medieval times, the London palaces of the bishops of Chichester and Lincoln stood along the eastern side of the street.
This attractive Italianate building was built in 1855 by George Legg, who also designed the King William IV in Grosvenor Road.
