I am still in search of the best cup of coffee in Toronto, having lived on the west coast for a while I have been quite spoiled. I usually get an espresso or an Americano with half the amount of water they normally put in. A friend mentioned Mercury was quite good so when I was in the area I gave it a try. Have to say it is up there for the best I have had in Toronto but I can't say it was up to the standard of the better coffee houses on the west coast, but definitely good coffee. Seems like a cool shop to do some work, not a huge place but cozy. I wouldn't go out of my way to get the coffee here but if I were in the area looking for a good cup I would drop by.
