Beer is cheapest in the Northwest, with real ale as cheap as a quid 75.
Despite this, the cheapest pub I’ve been in the last few years was down in Croydon. The first round was a pint of Guinness, guest ale and one of those Smirnoff Ice thinigies. When my change from a tenner included a five pound note I stared dumbly at the cash and tried to work out which drink they hadn’t charged me for.
We spent the rest of the afternoon, and a bit of the evening, in that pub.
