I tried an Americano at Grinder today and it was decent. The espresso is great, but not my favourite in Toronto. This is more of a personal preference though.
The atmosphere and area is really cool and the people working there were very friendly. There was a ton of delicious looking treats and I picked up a home baked granola bar (delicious!).
Their prices are a little higher than other coffee places in Toronto.
I look forward to going back.
