brussels IS beer.
you'll have a ball.
if you can't bring home the beer you will at least be able to bring home some of the glasses so you can enjoy the beers at home the way the brewer intended. the "beer temple" off the grand place has a great selection, but ain't that cheap. there's a chain of supermarkets called "colyrut" (bit like lydl only cheaper) and they sell most of the glasses. prepared to be sickened though, cos they sell the best of belgian beers by the case at unbelievbly cheap prices. there's about half a dozen stores in brussels as far as i know(lived there for a while). might be handier to get a cab. nearest one to the grand place is about a five-ten min drive. is accessable by metro but hard to explain
