This hole in the wall Dunkin Donuts in Mastic Suffolk county is amazing. Its spotless, fresh food, and the 2 men, Matthew and Marco, working behind the counter are second to none, complete gentlemen who take their jobs very serious. They explained all the different drinks and the Caramel Frappe they recommened was out of this world
I would give them 10 stars if I could!!! HIGHLY RECOMMENDED!!!

I rarely leave reviews, but I I had one of the most frustrating experiences at this Dunkin. The wait was already way too long, but when it was finally my turn, things got even worse. I ordered a latte with cold foam, something I’ve gotten at plenty of other Dunkin’ locations on Long Island with zero issues. The staff told me they “couldn’t” add cold foam because it would melt. I explained that I actually prefer it that way because it adds just a touch of sweetness without needing syrup. Even after I made it clear I didn’t mind, they still refused and said “Dunkin standards” don’t allow cold foam on hot drinks. If I’m paying for my drink (and paying extra for the cold form), it really shouldn’t turn into a debate about how I want it made, especially when every other Dunkin’ has no problem doing it the exact same way. At that point, I felt like I was arguing over something I order all the time, so I just walked out. If a chain can make a drink one way everywhere else, it shouldn’t become an issue at this one location.
I won’t be coming back, and I’ll be letting others know about this experience.
