I recommend the buffet breakfast at La Manoire Victoria in the Old City. Don't let the price frighten you - this is the BEST buffet breakfast I have ever eaten. I have dreams about the crepes (very thin pancakes, rolled up and drenched in maple syrup). There is a wall of different food stations - fruit and yoghurt, hash browns, bacon (Canadian and strip bacon) breakfast sausages, waffles, crepes, eggs of every description, and entire huge table of cereal and breakfast pastries. We stayed at the Manoir for Skate Canada the last time it was in QC and had breakfast in the hotel every single day because it was so good.
