Myriade is my long time coffee home. Predating--or at least arriving on time for--the new-wave coffee scene in Montreal.
The staff is friendly, fast, and familiar. The coffee is strong, simple, and satisfying. There's typically (outside school hours) plenty of space to sit and relax, thanks in part to the lack of available Wi-Fi.
Myriade lacks the pretensions and complexities of other coffee houses: outside your regular espresso/milk based drinks, you won't find a vast selection of roasts to choose from (usually 2-3 on a given day) or methods to brew them with (The Vario 60 is all I can make out on the menu). When it's hot they have cold brew. In the wintertime the mocha is heartwarming.
My impression is that Myriade wants to be a staple in your life. You can find more exotic--and better--coffee elsewhere, but there's nowhere as good to plant your coffee fix roots.
