Hogarth
You're running out of time to see the Hogarth exhibition at Tate Britain, and Sunday is the perfect day - after a weekend of debauchery it can be quite comforting to realise 18th century London was far more hedonistic. His paintings seem strikingly modern in their depiction of drunken and bawdy behaviour, brothels, and crime alongside drawings, engravings, and etchings depicting London life both high and low. Works by living contemporary artists inspired by Hogarth are also on display, including Yinka Shonibare and Paula Rego.

Slash Fiction
Slash Fiction is small group show at the excellent Gasworks gallery which nestles behind the Oval cricket ground, cowering beneath the gas domes. Highlight is entry to the semi-fictional country of Elga-land-Vargaland.

Alvar Aalto
The humanist Finnish architectural maestro gets a well deserved major exhibition at the - some might say - decidedly less humanist Barbican centre. If you ever despair of London's architecture, see this, and hope.
