I come here often before work and it is always a pleasant and fast experience. The employees there recognize me and are always very nice, even before I became a regular. I don't keep coming back just because it's close to my job but the kind service is great, they are always fast even when there are several people in line in front of me, and the value is great. Their coffee is way better than Starbucks' and costs less... and a donut to consider my breakfast? Yum.
I also always get a coupon on the bottom of my receipt to get a free donut with purchase of a beverage and so I always do this for my breakfast runs. GREAT value. I've never had their breakfast sandwiches but my coworkers said they were tasty... they are expensive for what they are though. I'm hooked on Dunkin coffee and this is a great location.
