I don't make a point of looking at online review sites very much, mostly because I don't trust them. (There are so many ways that a review can be biased: anything from ignorance to conflict of interest to personal vendetta, etc.) That being said, it's always nice to get a compliment.
My boss Cathy showed me this review today on yelp.com that included the comment, "Paul, their groovy super-barista was working, and he does a great job. Coffee was really great today. I appreciate they have constantly tried to improve and it's obvious that they have put thought and consciousness into their product."
Thanks, Guya I., whoever you are.
