I live near this Dunkin but I remember why I never go. It’s really gone downhill. My boyfriend found a hair in his coffee and my hash browns were smashed in the bag. I’m sympathetic to the fact that when we went it was a bit busy, but waiting for 10 minutes for just hash browns and opening the bag to a smashed order was disappointing.

The food was good. Order completed, nothing missing. Some of the bread was a tad burnt, but we did get extra hot chocolate when they thought we were missing it. Thank you.
I do think they could’ve announced a little more clearly that our order was ready though— especially since we (my mom and I) were the only ones there.
