Numerous coffee houses and a few roasters are sprinkled among the sprawling metropolitan area of Columbus, Ohio. (Be sure not to confuse "sprawling metropolitan area" with "large metropolitan area." It's just sprawling.) I'm on a mission to go around, check out the different options, and figure out what each has to offer. At each place I'll try a single or double shot of espresso and sample (probably a 16 oz. one) some coffee.
