I was in London yesterday. Lunchtime was spent in William IV, Leyton High Street. Standard strength cask beers were £2.45/pint and a bottle of The Kernel Double Scanns IPA 10.1% was a bargain at £3.50. The Euston Tap had a number of exclllent draught beers at £3.20/pint.
Later that evening and back in Chester the cheapest guest beer in Harkers Arms was £3.40. Checking the website of Manchester's Port Street Beer House, Double Scanns is out of stock but '#100' which is also 10.1% and from The Kernel is listed at £6.50 per bottle.
Time to move down South?
