There's a pub I love in Pimlico, simply called 'Cask'. They've got some speciality beers that I've always wanted to try but the prices have always put me off.
Now that this extremely generous 'someone' has come along though, I think I might be tempted into drinking a (nice big 750ml) bottle of this American beer:

It's a bargain (when someone else is paying, of course!) at £69 per bottle ;-)
Or, in the same pub, I could enjoy a double whiskey (18yo Macallan), which would only cost the mysterious 'someone' £28. However if the whiskey was going to be a chaser to the American beer above, it would seem best to go for an American whiskey too, so perhaps I should choose a double William Larue Weller for £35.60?
