A recent report has come in, "The pub is not closed - it is open for match days only at this time. Very nice local pub. Nice atmosphere. Friendly bar staff and the beers not bad either." Match days are both Saturday and evening matches. Their Twitter account is still live but with no additions since mid 2017.
From a walk around Tottenham on 30 April 2019, the Olive Branch is still closed, nothing apparently happening, still carries the signage from its Feb 2015 reopening so perhaps that didn't last long.
Friendly pub with pool table and two dart boards. Just up the road from the Park Lane entrance to the Spurs ground. Reopened after a period of closure in November 2014.
Olive Branch, Tottenham
