This is a tough one. We've come here twice for their latte special this week. Both times the coffee was not very good. This was surprising given past experience with Dunkin coffee. The donuts were fine (though they have a very limited selection). I would give this two stars, but the staff is very friendly and helpful. Unusually so, in fact, compared to other Dunkins we have visited. So I felt I had to bump them a star for that.
But for coffee I think we'll be visiting the other Dunkin near our office tomorrow.
