Hey Stephen,
I've been living and working in Brussels the last year, its a @*!£hole! And Im not kidding, to think this is the centre of "Europa", heaven help us!
Thankfully other cities in Belgium, and the rest of it in general, is not like Brussels, I was relieved to find this out myself.
Bruges is lovely, very very pretty, a nice place to walk around, do the canal boat tour thing, go for a lovely meal etc etc. As is Ghent, very nice too, not as touristy as Bruges. Antwerp is also nice, better for shopping in my opinion than Brussels.
Have a nice trip!
