Yes, it's another one of those made-up holidays. And yet, when I walked into Dunkin' Donuts this morning I was thrilled to find out that, in honor of National Doughnut Day , I could snag a free doughnut with the purchase of any beverage. Apparently the Penn Station Krispy Kreme is giving away treats as well, no drink purchase required. We have no idea if any of our favorite ma-and-pa doughnut shops are participating in this promotion, but hey, why not drop by and find out? Worst case scenario: you pay for a sugar fix.
