I visited Ezra's Uncle (the shop not the man) for a quick latte. The person behind the counter was affable and efficient.
The latte was plain and pretty smooth, just like it should be. The drink menu was intriguing; lots of Canadiana flavours and other specialty versions with espresso that I wouldn't otherwise expect.
I don't know anything about their beans, so that might be another thing to look up for my next visit.
Laptop hobos beware, the shop is very tiny. It's more of a grab and go kind of place.
Study/Work friendly? Nope.
