Maybe an obvious choice, but the Barbican is always good. My favourite space in there is the curve gallery, last time I went was for Cory Arcangel's 'Beat the Champ'. I love the architecture, although not many people do. I think it was voted 'London's ugliest building' in 2003.

A treasure trove in the The City of London. The Archive of London. Strongrooms hold kilometres of shelving; boxes of matter that has somehow been catalogued and categorised in a traceable manner by the public, for academic, genealogical and other research. This beautiful book is from a box on Epping Forest. On the same visit, I looked through photographs of Blitz singsongs in Bethnal Green Underground station, 1980s anti-Thatcher / pro-GLC gig posters and paper concertina optical models of the Crystal Palace.

Event space and studios with eclectic group of musicians, artsist, DJs primarily around jazz, world, folk, experimental music 

Everything you expect from a neighbourhood café and more.

If you are lucky enough to get a table at this tiny 6 table only Café you are in for a real treat. The coffee is great, the cakes are delicious and the staff is friendly in this traditional wifi free (meaning no wifi here) Café. On a quiet day this is the best place to delve into your favourite novel while being caressed by the easy listening aural pleasure of Classic FM. But the real reason I come here is to overhear the conversations of the other customers. More than once did I have to put my book aside to pay closer attention to the charming, wonderful and often nuts conversations going on around me. I've overheard all sorts of discussions varying from 'Psychoanalysis' to 'Proustian ideas', 'Science Fiction' to 'Greek Mythology' and 'African Studies' to 'the takeover of DC Comics'.
