Fuel Up for Free in Boston on National Coffee Day

Several local cafés and chains are celebrating this Friday.

Have another cup of coffee: This Friday, September 29, marks National Coffee Day, and you can get a hug in a mug for free across Boston. Although the origins of this celebration are based more in the Internet than in any history, it will extend beyond the screen. Local retailers are offering up deals to satisfy your caffeine craving.
