When Cartel Coffee Lab opened its doors in 2007, it changed the game for coffee shops across the state. In Arizona, roasting beans was unheard of, and unless they'd visited Portland or Seattle, most Arizonans didn't really have a clue that coffee could be so good. With its über-hip industrial space and walls adorned with artwork from the Tempe community, Cartel is still top dog in this 'hood. A couple of other shops have tried, but not a single one can come close to the quality beverages made by the expertly trained staff. You may have to wait a minute or two longer for your cup of joe, but you can't rush the best.
