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
There are many quirky book stores in London, but I really love the selection that Daunt Books have, they often have bespoke editions which you won't find in other book stores. Also, the people that work there are so helpful and knowledgable. I can never stop myself from walking in!
Nice old trees, lots of space, good for walking, running, hanging out with your kids and most of all, the perfect place to lie in the grass and chill out.
