Things to go out and do when you can't afford to have the heating on all night.
Tonight: Start the weekend early and feel dead trendy and cultural - go to the private view at NO:ID gallery, 31 Commercial Road E1 from 6pm to see Jayne Taylor's 3D (stereoscopic) photographic portraits of people in their own homes (part of Photomonth) then hop along to the arty party afterwards across the road in The Castle.
Or take advantage of late opening of the Barbican Curve where Robert Kusmirowski has transformed the space into a World War II bunker. Free, till 10pm.
Friday: Not a tourist? Hell no. Then investigate the Not For Tourists London city guide at their own launch party. Drop by Bar Kick, Shoreditch High Street from 5pm and watch out for our review of the guide coming up quick smart on Londonist.
Saturday: Celebrate books by contemporary artists, poets, writers, composers, book designers and small publishers featuring artist-publishers and small presses from UK and abroad at the Small Publishers Fair 2009 at Conway Hall, 25 Red Lion Square, WC1 between 11am - 7pm. Free entry.
Fans of dressing up, remember it's the Mad Hatters' Tea Party in aid of Oxjam in Clapham - just £5.
Sunday: Stimulate your grey matter whilst damaging it with booze down at the Quizzer Sisters Sunday quiz. It's only a QUID to enter and you could win gig tickets and free drinks. The theme? 'Winners & Losers' digging deep into the failed pop careers of soap stars, the fashion trends that were never meant to be and the those Tomorrow's World gadgets that never caught on. Retro cocktail bar The Black Door, Kings Cross is the venue from 7pm.
Monday: Peckham Literary Festival kicks off today with a free philosophical event at Review Bookshop from 7.30pm.
Tuesday: There are 2 interesting, free public lectures going on at LSE tonight from 6.30pm. Choose either "Obama and the Arabs: the historical context" in the Hong Kong Theatre, Clement House or "Cities, Design and Climate Change" in the Sheikh Zayed Theatre, New Academic Building.
