    The people that works here should be fired. They dont know how to make coffee and they dont know how to make sandwiches. My eggs were cold. My bagel burnt and my cheese un melted. This was after sending my food back to be remade. Do not spend your money at this location.

    I did a mobile order. When I got there to pick it up at 930 in the morning. I was told they didn’t have any of the donuts that I ordered for my dozen. I was told if I want a refund then I need to do it thru the app. The bacon was raw on my burnt avocado toast and the Dunkin wrap was still frozen. I’ve reached out to Dunkin support emails and phone calls and no one has called me back.
