Acquired by Fuller's from M&B in February 2009, a 17th century pub listed on CAMRA's Regional inventory of historic pub interiors, originally two buildings now forming one pub, The old servery (still in occasional use) is an exceptional and highly unusual piece of pub architecture with its glazed sash windows and aged shelving and panelling. The two rooms either side retain much from an inter-war makeover. The newer areas to the left to not impinge on the character of this older part.

it was also known as the Upper Flask, the Lower Flask being the pub in Hampstead.

More plausibly, the 18th century painter, engraver and satirist William Hogarth, and revolutionary thinker and philosopher Karl Marx are said to have been regulars.

Large asphalted front yard and garden which incorporates a covered area too. 5 handpumps on the main bar counter and 1 on a smaller one by the entrance door. Underground: Archway or Highgate.
