If I recall I can pick it up in either the Duty Free or the Albert Heijn (local Dutch supermarket). Belgian beers are just fantastic!
When stationed in Germany working at a NATO training center, one of my good friends was the US Defense Attaché at the Embassy in Brussels. Every other month or so he'd being a bunch of Belgians through for a joint exercise with US troops, and I'd get a sizable delivery of Leffe. Nowadays you can probably find Leffe at the grocery store, but it really did the trick at the time. Lots of good memories with that one.
The Dutch beers are mostly quite watery, but not bad on a very hot day. I found it funny that our 'Amstel Light' is just 'Amstel' in the Netherlands...lol But with Belgium next door, there is just so much goodness to choose from.
