For breakfast in Montreal, Universel wins. These people take pride in their work and it shows. With most breakfast dishes comes fresh cut fruit on a skewer. Someone spends their morning carving the fruit with a smile. Extrapolate that attention to detail to the rest of your dining experience, and you've got Universel.
If St. Laurent has the disease, Universel's got the cure. The portions are heaping but lack the grease common to many hangover-curing breakfast joints. We usually get some combination of eggs benedict or omelets. The gf and I are particularly fond of the universel, an omelet with every breakfast meat under the sun, and the billy goat, eggs benedict with smoked salmon, goat cheese, greens, etc. The already large portions are accompanied by the aforementioned fruit skewer and a heaping pile of quartered potatoes. Also check out their milk shakes and smoothies, though they are meals unto themselves.
