It's a Dunkin Donuts. Nothing extravagant has ever been found at a Dunkin, so adjust your expectations accordingly. They're not famous for their breakfast sandwiches or their bagels. If you stick to coffee and donuts, you'll come away happy.
I generally pick a chocolate frosted with sprinkles or one of the cake donuts, as I'm custard donut averse. My husband is a fan of the Boston cream. Go elsewhere for fancy espresso drinks, but their drip coffee is probably the best you'll find.
Employees have always been friendly to me here, even when it's before 6 AM. The drive-through line gets a bit long, but as long as I can get a medium coffee and a few donuts for under $5, I have no complaints.
