I am giving this place a five, not because the food is so fantastic, but because it is the best place to get breakfast in the old city. Unfortunately this is not a difficult achievement because most French do not crawl out of bed until 11am so they do even know what breakfast is. Therefore, 95% of Quebecois eateries that pretend to serve breakfast suck so bad it hurts. I went to one crepe place twice during standard hours and it was closed both times and had no hours posted in the window--that's how bad it is.
Cafe St. Paul is sort of the exception. The are open during breakfast hours (a freakin miracle) and they have a grille (mon dieu! what is a greel?).
The cooking is quite competent. They serve all the standard breakfast faire and it is well-executed. It is amazing that it is French owned and operated. Normally you would have to import Americans to pull off such a feat in Montreal.
Service is polite and friendly. Decor is plastic plants, linoleum and laminates.
