Speaking of which, I'm back in Montreal at the end of May for 4 days
Coincidentally, so am I. Except it's not "back". Hmmm.
As for "best pizza's in the world": dear Celt Z, the Italians would like a word.
As for local food - the obvious ones first:
Belgian Fries: French Fries, but correctly named.
Belgian Chocolate: it's what all the women want*
Belgian Beer: it's what all the men want*
Belgian Waffles: because waffling's what our politicians do best
Vol-au-vent: it may seem strange as this is such a "classic" all over the world, but yes, this is originally Belgian - not French. Again. Bloody French.
Bread. Seriously. There's good bread in France, Germany, most of the Netherlands, and Belgium. All the rest of the world seems only to know how to make crappy mushy whitish stuff only fit for toasting. Yes, even your "regular" bread. Believe me - it doesn't compare. At all.
Speculoos. Type of gingerbread but better.
There's plenty more - many "classic" dishes, usually thought to be "French cuisine" are actually Belgian in origin or have been shaped by Belgian customs and habits.
