Being the queen of the Bloor/Bathurst street corner, I obviously have wandered into the Green Beanery quite a few times.
One additional thing to note here that hasn't been mentioned - they also serve ice cream! Ice cream from Greg's Ice Cream too, the good stuff!
I order regular coffee, not into the fancy coffee drinks, but the regular brew here is very decent. No complaints. The staff have always been quick, friendly and seemingly knowledgeable on products to me.
The interior has high ceilings and has a modern loft feel to it. One large area is used as a store space to sell various coffees, glassware, grinders and espresso machines. The other side of the room has seating for 15-20 people.
