"Kriek" , a very nice Belgian Cherry beer. It comes from different makers but my favorits are the "Lindemans Kriek" , wich is very sweet tasting, and the original "Belle-vue", which has a much more bitter taste.
I also like dark brown abbey beers we have here...
That said, I'm not a real drinker (hehe, anymore anyway..). These days I really can have only one glas of beer and enjoy it alot withouth getting dead drunk ... As for a "normal" beer I prefer "Jupiler".
We have a very rich beer history in Belgium, there are over 1500 (!!) beers in our little country. Here you can find a complete list. Also most beers have their own shaped and printed glasses who often are artworks themselves !

Last year the "Westvleteren Trappist" has been chosen as best beer of the world .
I haven't tasted it yet, it's produced very limited and very hard to get your hands on a crate...
