I was in Porterhouse Central at the weekend and noticed they've added a third beer engine. They've also moved them down to the end of the bar opposite the front door and have a big blackboard saying what's on. Got my first taste of cask Brainblásta, though just a taste as it was the tail end of the cask. It also wasn't great, possibly for the same reason.
Anyway, good to see more cask in circulation.
