I love this Dunkin! The staff are always super friendly. They have several tables around (inside and out) and wifi, so bring your laptop and sit for a spell. My favorite donut in the world is the brownie batter. Sadly, it's only available around Valentine's.
The only downfall with this location is the parking lot. Sure they have spots right up front by the door, but they're a pain in the rear to get out of. Make it easy for yourself and park across the way -- you'll see what I mean when you get there. Then just play Frogger across the parking lot, bobbing and weaving between speeding cars, to get to your cup of brew. The extra walking won't hurt ya!
