The Dice Bar.
The barman said that Revolution is renamed Bombardier which, tasting it again, is totally possible.
He also said that D'Arcy's is from "some brewer up north" but for such a chocolaty stout, I can't think who that might be. I'd be more inclined to agree with delzep if anything.
They also had four other DBC badges: Wicked Cider, Celis White, Augustijn Blonde, and Sparta Pils.
The Dice Bar's website linked here[/url:350t9k95], which has quite a bit more information. And yes, it does conflict in places with what I wrote above. I'm just telling it how it happened.
