The map above shows the closest of nine major coffee giants within a 10-mile radius throughout the U.S. and southern Canada. As you can see here, many popular American chains are represented here, Starbucks, Dunkin Donuts, Caribou Coffee, Coffee Bean & Tea Leaf. (Blenz, Coffee Time, and, of course, Tim Hortons are Canadian brands.)
Starbucks is scattered all over the map, but that doesn’t mean it dominates every state. Dunkin Donuts and Tim Hortons take over a huge chunk of the country too.
