If we're complaining about things being too small, I'd like to nominate the croissants at YUL Cafe (not that size is the only issue with them).

I'm not much of a breakfast eater, and all I want in the early AM is a croissant and a coffee and I can go find a quietish part of the terminal and get out of everyone's hair. YYZ Cafe has decent coffee and croissants. YUL Cafe has crappy machine coffee and the same tiny stale fake croissants they serve in the air. Extra stupid because you'd imagine Montrealers are much less tolerant of a bad croissant.
