Alternative Grounds deals in fair-trade coffee mostly, but also some teas, too. The selection varies from day to day, but is always good quality stuff, and you can get coffee to go at the cafe, or buy beans to take home.
Alternative Grounds is also heavily involved in community stuff, with special events, contests, and art on display. But what's great is that they put their eco-socio-friendly money where their mouth is: you can get a discount if you bring your own container for take-out, and there are days where biking over with a reusable travel mug will get you a free coffee.
