Try The Cave on Great Western Road, they might have it. Always had a great selection of odd beers when I've popped in. Failing that, they may order it in for you (but you'll probably have to buy a case).
Really? I always thought it was a really good zoo. Bloody expensive, aye, but one of the better zoos I've been to though haven't been for a while.
Might give that a try actually, I'm sure I know the place you mean!
As for the zoo, it might've just been a bad experience. The only monkeys we found in the enclosures were crude builders with JCBs. We even saw one peeing in a bush, quite close to children. Most of them were empty or with what appeared to be rather unhealthy and poorly kept animals.
We were desperate for food/drinks but the Cafe had closed early for no apparent reason and none of the vending machines around the sight worked and ended up swallowing our loose change. To make matters worse, it started raining and the remaining animals seemed to disappear. They had the cheek to pester us for a donation!
Funniest thing about the experience was my GF, wandering around a zoo with a fur coat on. The looks were epic!
edit: It was a fake fur coat, incase any of the animal rights brigade want to jump in for a go!
