Going out for the day to visit parks is a great way to spend a sunny afternoon, particularly on a weekend. These have some of the best summer produce available (much better than any supermarket, for sure!), and are all over the city. Make sure to check out the Brixton Village Market, open every day of the week, and with live music on Thursdays, Fridays and Saturdays. Greenwich Market is another one to pop into, offering unique crafted pieces and foods that are a must for every visitor, or local, in London.
