Actually--if you read a bit further, you'll notice that the Chimay was actually part of the "wine pairings" for dinner. Chimay was paired with a certain food course. As far as I am aware, Chimay isn't available at V&A by the bottle. All they have there is from the bar of Citricos, or Mizner's lounge. And that, I'm afraid, isn't much.
Should add that a few years back I tried to get V&A to carry Chimay (and other gourmet beers), but it appears that the "pairings" was about as far as they wuld go--
