A big beautiful late 19th Century hotel that endured a slow decline into draughty old man's pub, The Salisbury has been done up in the last couple of years and this has been carried out sensitively and stylishly, unlike a lot of the crude pub makeovers of the last half decade. Many of the old features remain - lovely glasswork, big centrepiece bar, high ornate ceiling and balding 40-something blokes lounging around and talking about football. Not the greatest Guinness in the world but there are usually some nice, though expensive, ales like ESB and Honeydew.
Harringay comes from the Old English 'Hoering's woodland enclosure'. A nice article about the difference betwen Harringay and Haringey here.
Edit - It's been pointed out to me that there is further info for 'Harringay origins' enthusiasts at Harringay Online.
