The quality of the coffees at R Squared have surpassed all my expectations. This is my new go-to place for artisan coffee excellence.
In addition to the delicious espresso drinks, I especially love their pour-overs. I had the Ethiopian Sadama in a pour-over several times and it was consistently outstanding.
Best coffee I've tasted in a long time. Also really impressed with GTA's own Social Coffee roaster (who RSquared uses); finally, a local roaster striving for really high quality.
P.S. I am [sadly?] a coffee geek who's been into coffee for many years, I prefer it black in order to taste the subtleties of great coffee, and as a result don't usually drink anything like Timmy's or Starbuck's black because all I taste are the caustic flavours of crappy coffee and/or over roasting. I say usually, because sometimes it's an emergency -- a matter of getting caffeinated or not, and in that case I'll load up on cream to cover the tastes.
