Whole foods has some of the best coffee in town. They always maintain two regular brews and one decaf brew. What I like about WF brewed coffee is that they make it strong!
They roast their beans at the Washtenaw store, I asume the beans at the Eisenhower store are roasted locally as well. You can always get a great espresso product at the coffee bar as well.
Other favs include, iced coffee, tea drings, sparkling drinks, Chai (which I don't dring) and mocha drinks.
Best thing about the Whole Foods coffee bar is that the people that work there are friendly and genuine. That goes for Whole Foods in general.
For people who complain that Whole Foods is expensive, get over it! Their coffee is not that expensive, the quality is great, service is great, they have a nice place to sit with wireless. What more could you ask for!
I am a regualar there. I can generally be found in the cafe making noise on my smart phone or working on my Ann Arbor real estate listings on my laptop.
