    I was asking the guy there to let me use the bathroom I need to wash my hand before I had a meal. He said no bathroom not for Customer what I know Dunkin they don’t give license. If the owner he don’t have restroom. This is the policy to help people, especially in this area keep everything clean, but they deserve less than one star and the guy worked there he not deserve to work at Duncan if there is less than one star, I will give him -100 star. I will leave that for Duncan department. Very bad service

    They made a brand new Dunkin and kept the same horrible employees. They do not want to work there, please let them go. Everytime I think they’re gonna just not mess up they always do. WORSE DUNKIN EVER.

    I’m very happy to say that they really did a great job redecorating the shop, it’s so clean and they have new people working there so the customers service is sooo much better.
