Walthamstow Wetlands are London's largest urban wetland nature reserve, home to many wildlife species. Only 15min from central London. The cafe is open daily for breakfast, lunch and afternoon tea.
SOAS university has a small gallery space dedicated to exhibitions about Asia, Africa and the Middle East. There's a small but beautiful Japanese zen garden on the rooftop (currently closed for refurbishment)
Having spent many years studying there, I have a soft spot for Central Saint Martins, which finally closed in September 2011 when the college relocated to Kings Cross. Despite being such a dive, the old building had such history and character and I grew very fond of its tatty charms. As plans for its take over by Foyles bookshop go ahead, I look forward to having a coffee in the new building's cafe when it re-opens.
