You'll struggle to find a venue that provides quality entertainment at prices as low as this, particularly in central London. I've seen Blink, The Kingdom and A Clockwork Orange for around ten pound a pop and at these prices it's competeing with cinemas and winning. You can even get away with booking only a day or two before hand and still manage to get great seats as they're often unreserved. Make a night or day of it, go to Soho theatre.
