Reviews for Dunkin’s Iced Coffee

Oddly enough, a frequently poor experience at their other location on Broadway has compelled me to write a 5-star review for them too. I’m somewhat of a creature of habit with my coffees — an iced coffee with oat milk and some sweetened syrup, usually whatever is in season. This location has always been consistent – the iced coffee tastes full-bodied and not watered down (unlike the Broadway location), and they add the accurate amount of sweetened syrups when I ask for it. Service is always friendly and accommodating as well. We’re so happy to have found a Dunkin’ we can call our “go-to” around here as newer residents of the neighborhood!

Really like this location. I stop by frequently on my way to work for my iced coffee. My order is always correct, not too much of a wait (this is usually around 6:30am) and the employees are pleasant.

Very good food and drinks. The best iced coffee and the people are really nice. Good donut variety too, most don’t have these many donuts. Coffee tastes fresh every day.

My husband and I stopped by this DKD, and I almost ordered the way I would order my coffee in Boston, which is a “French Vanilla Extra Extra” but that’s another story, LOL! Nevertheless, they prepared my French Vanilla iced coffee perfectly! It totally reminded me of how I used to order my DKD coffee back home in Boston in Back Bay. So happy that we stopped, and it was kind of funny how they turned a “bank” into a DKD. Having a coffee that reminded me of Boston, made my day! Thanks guys, great job!
