This location of Dunkin Donuts is on my way to work, so I stop in quite frequently. The staff is typically pleasant, with the occasional "bad day" employee which is why I have given them a 4 star instead of 5.
The food/product is always consistent and the store is very clean and organized. This location is particularly efficient, with what seems to be an endless client base of corporate-grind people who need their donuts quick and their coffee even faster.
The coffee consistently wins awards and has been voted higher than Starbucks. I believe that their coffee is a bit sweeter than it needs to be, but the pricing is a pleasant relief from the shameless gouging of Sbux.
