This isn't your daddy's Dunkin Donuts with the stale donuts and dirty looking shops. No. Dunkin Donuts has come a long way.
They are clean. Service is very friendly. They offer more than donuts. From iced coffees to muffins and hot breakfast sandwiches.
My only complaint is that the wait time increases significantly when ordering hot sandwiches. If your in the drive threw it's not as bad but inside can take a long time. I once had to wait 20 minutes!
They need to work on a way to fix that problem.
