I would drop the "A" part from the name and just call this "OK Coffee"...for that's exactly what my experience at the place was like today...just...OK.
In a city deluged with coffee shops, I think it's important to have a friendly staff. I went for coffee and a sandwich with three friends today. The food was mediocre, the service atrocious and attitude-laden. I won't be going back anytime soon.
