For a coffee shop, they really don't serve very good coffee. All of the coffee and espresso drinks that I've gotten there have been disappointing - the coffee was lukewarm, there were coffee or espresso grounds in the drink itself, etc.
The service was quite slow the last time I was there, and I was the only person in line. The few times that I've been, the staff has always had a "holier-than-thou" attitude. What about, I'm not sure, exactly, but so it goes.
