Forty: Pub in Wandsworth, London

Forty is an art venue in SW17, and its programming leans towards live, curated work. The "Forty Presents" banner is a useful clue. It usually means someone has chosen a show or performer and built the evening around them. That makes it a good room for people who like going in without knowing the whole bill. The work tends to be playful and performance-led, the kind of thing that works best with other people in the room and asks you to pay attention. If you are deciding whether a night is for you, look at the odd bookings as well as the obvious ones. Venues like this often show their character there.
