Apologies if this has already been posted in another thread (I had a look but couldn't find it), but people in and around London may be interested in this promotion:

We had a mini-ramble around Hammersmith last night, calling in at the Brook Green Hotel, Thatched House and the Ram, and the combined total cost of ?? pints of Ordinary was 0.

Not all Youngs pubs are participating, but there is plenty of scope for a cheap night out in other parts of the capital.
