There is a noticeable void in brunch & breakfast places on the West Island; this is the best option that we've found. O&C provide many different versions of the standard salty "American" breakfast plus the euro addition of beans and creton. They don't "sweeten" the potatoes (like the Hotdog Station) and coffee is free.
If you arrive before 8:30, you can get the early bird deal (half price). Kids eat for free on Saturday.
The place is rather huge and packed on most days after 10am; that said, we've never had to wait for a seat. Service is super fast... we're typically in and out in 30-45mins depending on how busy it is. On nice days you can sit on the patio.
