    The staff here is truly wonderful🥰, consistently friendly and kind. I visit almost every morning. My only concern pertains to the restroom 🚻🚺 facilities. They do not appear to be as clean 🫧 as the rest of the establishment. On each occasion I have used the restroom, I have noticed flies 🦟, and the toilet paper 🧻 is rarely in the dispenser, often resting on the metal handle instead. There was even one instance where I found the toilet paper 🧻 on the floor 😩. I would greatly appreciate 🙏 it if the toilet paper 🧻 could be placed in the dispenser. Finding it on the floor and then having to use it is quite unhygienic 🦠. If this particular issue could be addressed, I believe this Dunkin' Donuts would be absolutely fantastic.

    I want to start off by saying that this is not my typical Dunkin. But it is the closest one to my house, and there are occasions where I come here instead of going out of my way to the location that I love. I can confidently say that every single coffee I have ever ordered from this location is incorrect. And I know it’s not the way I say it, because my other Dunkin gets it correct every time. I say good morning to the people at the window, and they never respond back.

    Idk what atmosphere so I just give it five stars anyway the croissant safe and toasted just how I like since I have swallow issues… This Dunkin Donut make it very soft and delicious just like the one from Commack and I like it like that because the other Dunkin Donut from Brentwood and Suffolk they always make it so hard and kinda Burnt… Like no offense to those but at this point since I have swallow issues I’m going to this Dunkin Donut and the one from Commack from now on 😭

    Went here last night with my bf and got apple pies, went to eat one today and found flies stuck in the apple filling. I been here multiple times and have noticed the files all over with no attempt to get them gone. This was a final straw.

    This poorly designed location nearly caused an accident every day. People line up and stop short in portion road blocking the right lane every day.
