Drinks are always made well. Staff is friendly enough but not super welcoming. Always try their best though depsite often having a long line. Prices are good, inside is a bit run down

Not the worst Dunkin', but it seems to be understaffed as there was only one employee there when I went. On top of that, they only have agave straws, which were off putting because I thought the specs on them meant that they were dirty.

Ok, clean, annoying beeping, like a fire alarm battery that's needs changing. Staff not attending to it. Other than that it's fine.

She asked me twice, so I know I was heard. But this is not light with milk. Also the other beverage, the tea 1 sugar - had no sugar. At all. Now on way to ferry wishing I just bought on the boat. Hopefully your experience is better.

I walked in and the place was empty except for one guy sitting there who wasn't eating or having anything. I approached the counter and the woman working looked at me, broke eye contact and didn't say anything for about 30 seconds until I spoke up. No energy, no anything. Maybe a hangover since yesterday was New Years? She mumbled something and I looked at the menu then started ordering. She said 'hold on' and started doing something else for a bit before taking my order. They didn't have the thing I wanted so I ordered something else. When I asked for food that had different versions, she didn't ask which version, she didn't say anything. The only thing she really said the whole time was hold on and then my price order. I paid, I didn't get my receipt. While waiting, I noticed the state of the store. The floors were so sticky wherever that my boots kept getting stuck, the floor was visibly dirty. There were broken outlets, walls and ceilings seemed filthy. Tables looked unclean. Displays weren't straight and were dirty. After about 15 minutes, I got my food and no drink. I reminded the male worker of my drink and he made it for me. He was fine, responsive. It seemed like the female worker wasn't doing anything. The energy was really low and really uninviting. I got my hot chai and it was lukewarm as he handed it to me. At this point, I was really put off by the whole experience of the place, and my boots literally sticking straight to the floor, that I went to leave and ... uh, there's no door knob or door handle to exit. It's just the flat glass door. Which is a total safety violation. So when you've got all your food and your drinks, just lean on the filthy door that has no door knob to exit. When I got to a table outside to eat (1-2 minutes later), I realised that the food I got was actually completely ice cold in the center and the cheese wasn't melted. Cold coffee and cold food. Straight from the counter. Awful energy. Completely filthy. Felt unsafe and unwelcoming as a customer. I'm never going back. Thanks. Starbucks is literally directly across the street.

After sitting down with my siblings, I was told by an employee that I had to order something in order to sit. I told the employee that it was not a problem, and he said to me,” better make it quick.” Never been so disgusted by the behavior of an employee and will stick to Starbucks across the street. Customer care is better.

This is by far the worst dunkin I’ve ever been to. The service is terrible they are always on their phones and when they do help you they move as slow as a snail. It looks like the place hasn’t been cleaned since they opened. Not sure if they ever clean the stove as burnt pieces of it were stuck to my food. I don’t know how they made my nieces plain bagel toasted with cream cheese taste bad but she wouldn’t eat it. The food and drinks taste like everything is old !!!! Terrible

The lady that worked at the counter of Dunkin donuts store next to port Jefferson ferry location didn't want to unlock the bathroom door until I put my order in and paid for it. I explained her that I am about to get the order by text from my family but she didn't believe it. She insisted that i order and pay first. After I paid for my order she unlocked the door. This is unacceptable for Dunkin donuts chain store. Starbucks would never do this. I was faithful customer for 30 years to Dunkin donuts and purchased food for my whole family, i didn't expect this kind of rudeness from Dunkin donuts. Shame on you Port Jefferson Dunkin donuts. Disgrace.

Ordered Strawberry coolatta and it tasted like apple cranberry they labelled it wrong on their product as Strawberry told the lady to sample it or other people are gonna complain and didn't even care lol stuck with something I didn't even really like so much for my sweet tooth being satisfied

Filthy filthy filthy. They had no bathroom tissue. I asked the owner and they said to use napkins. Went In with a group and I guess we were a little loud, manager or owner told us to quiet down. Never again will I go into this dunkin donut shop.
