Cafe Myriade is the go-to coffee shop around Concordia. It's one of the few places with decent coffee amongst all the Starbucks and Java U's in the area. The coffee had a good flavour and I actually ended up getting seconds. I haven't tried their selection of baked goods, and it was hard to resist cause they looked delicious.
Cafe Myriade has got a chillaxing atmosphere, but be warned, it's rather small and usually crowded with students.
