We went for a Bank Holiday pub crawl in search of London’s cheapest pint. A Local TV reporter visited The Tarmon, on Caledonian Road, on a drizzly day where he bought a beer for £3.50. He also went to the Hackney Church Brew where he discovered a cheap Thursday night offer - but it didn’t extend to the weekend. And the final stop was at the Spit And Sawdust, on Bartholomew Street - a central London bar that would appear to offer the cheapest pint in Zone 1!
