I've always considered Chimay Grande Reserve to be the Mercedes S500 of beers...it just sets the standard by which all others are judged.
There have been few domestic beers in the Belgian style that I've found to be worthwhile. Unibrew is perhaps the most consistent, and the original Celis from Austin was an excellent Wit beer.
I'd like to see the recent Belgian IPA trend go away.
The only time I tried making beer with a Belgian yeast it ended up tasting like banana Nerds candy
