You could call me biased, given this is the 3rd Highbury restaurant in my list, but if you're doing so then you've clearly never tried the Biang Biang Noodles at this unassuming little BYOB gem
I grew up in Brighton which is full of cheesy bars like this. If you can handle being surrounded by multiple screens playing Kylie at full volume, its pretty much the cheapest bar in central london. The cliental is so varied its great for people watching and completely un pretentious.
My walk through the Heath often continues on to the Camden Arts Centre, a really fantastic exhibition space that runs workshops and courses as well as having a great café and bookshop to boot. I collect their exhibition booklets called File Notes - beautifully designed by James Goggin and Sarah De Bondt - some memorable shows include Eva Hesse Studiowork, The Bruce Lacey Experience and Serena Korda’s Aping the Beast. The latter concluded with a procession from the gallery up to the Heath, culminating in a re-enactment of The Battle of the River Plate in a pond. This is my photo of the Beast and the Boob Meteorite.
