Don't remember their names now, but the cask-conditioned ale's I had in several pubs on my recent vacation to England were by far the best I've had. Man, I wish they made it like that over here!
A local microbrewery here in the Seattle area, Hale's Ale's make a Cream Ale that's the closest I found yet.
Come now Kuan, I love Guiness too (have 13 or so cans in the fridge right now), but can you really qualify that as 'exotic'?

Love the avatar btw!
Hope your celebration was reasonably sane Bear
