I go to quite a few Dunkins in the area and this one is by far the best. All the employees here are friendly and remember me. Although the drive thru is slow sometimes. I feel as though the long played our speech at the intercom might have something to do with it. Some times I feel like they're joking with how slowly they say "Weeeelllcome tooo Dunnnnkin Donutsssss, whattt are youuu drinkingggg?!" But other than that they're pretty quick and don't cut you off while you order.
I've sent my coffee back a few times for tasting watered down and have never had a problem. They're always so nice and quick to remake it for me.
I would give 5 stars if it wasn't for the annoyingly long speech at the intercom.
