I personally love photo arts and this gallery puts on some amazing exhibitions by the best artists, such as Vivane Sassen and Gregory Crewdson. The Gallerys’ six-storey space is located right by Oxford Street, so if you are doing some shopping in London, you might as well stop by this gallery. The upper floors consist of two new galleries, while the ground floor hosts a nice café/restaurant. Together with the print sales, the bookstore occupies the basement of the building. I can spend hours just looking at the books, how it is designed, bound, as well as the prints for sale. You can buy all kinds of film; medium format to polaroid film at the store. After some hours at this gallery you just want to go home and start making some photography! 

Whipps Cross boating lake is a true hidden East end gem. Located on Whipps Cross flats midway between Walthamstow and Wanstead.

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)

If you like some nice cool beer, portuguese sweets (the once with yellow custard inside) tasty and affordable sandwiches, good strong coffee and football, at all hours. Max Snack Bar is worth checking out.

London has great green spaces. There are large royal parks and small public gardens, hidden allotments and roof terraces. Each one has its own identity and characteristics and everyone has their favourite. In summer they become extensions of people homes, you see girls sunbathing from 9 am and the endless picnics mean you can eat 3 meals a day in the park. My favourites - St James Piccadilly Gardens, Hyde Park, Barbican Conservatory.
