Addis Ababa, Ethiopia

The birthplace of coffee — the traditional bunna ceremony is a 45-minute ritual of roasting, grinding, and serving.

Ethiopia is the birthplace of coffee itself -- the Kaffa region lends the drink its name. In Addis Ababa, the traditional coffee ceremony (bunna) is a 45-minute social ritual: green beans roasted fresh, ground by hand, and served three times in small cups with incense. No city on earth has a deeper claim to the bean.
