I recommend trying the Cookie Butter Crumble Latte, it's delicious and buttery topped with crookie crumbles and foam. It's sweet and creamy with a hint of dark roasted coffee. The donuts are delicious and worth the money.

I usually have five stars for this Duncan as I frequent it every day sometimes twice a day. I'm a very loyal customer. But today is Christmas I know they closed at 2:00. We were in line at 1:50 came up to the ordering window right at 2:00 and they turned us away. Not only us but someone else in front of us. I thought that was very rude as maybe since it's Christmas they couldn't at least said well they were in line for 10 minutes already let's at least give them their coffee. I think that absolutely sucked

I’ve been coming here for about two years now, usually 4 to 5 days a week. For the most part, it’s been a good experience. But over the last five months or so, I’ve noticed a drop in customer service. I used to work in customer service for over 15 years so I know how to treat people.
Some of the staff are great and really friendly, but a few just don’t seem to have much customer service training. Lately, I’ve mostly been dealing with staff at the takeout window or inside who come across as cold. They never say “thank you” or “you’re welcome,” and they never smile. They don’t seem outright rude, but it often feels like I’m bothering them just by showing up.
I always try to be polite and respectful, but I don’t feel like that’s been returned as of late. I really think some refresher training on basic customer service would make a big difference.
After being a regular for so long, it’s disappointing to feel this way. I’ve decided to take a break from coming here—I’d rather support a place where the staff seem glad to have customers.

Visited the Dunkin’ Donuts on 51st & Olive on December 30, 2025 between 1:33–1:35 PM, and the customer service was extremely disappointing.
The employee handed me my iced coffee with a dirty look and had a clear attitude when I asked a simple question about the free donut promotion. Despite the poor service, I still left a tip because my iced coffee tasted fine—however, the hot coffee wasn’t even hot, which is basic for a coffee shop.
Both employees were more focused on their personal conversation than on making drinks or providing service. There were no other customers at the time, yet they continued a loud, blown-out conversation instead of paying attention to the order in front of them. Conversations like that should be saved for break time, not while preparing customer drinks.
I expect better professionalism, attentiveness, and basic courtesy. Good drinks don’t excuse bad attitudes and lack of customer focus.
- They where two YT women- full of tattoos- they look like second chance individuals not grateful for the job

Corey the young man in the window taking the order Has a Great Attitude and Positive Vibes that I would Definitely Be Looking Forward to Seeing Him Again Thanks For Being So Awesome Young Man and I will be tipping him by himself because he deserves a promotion. I tried to give him a tip but he said that he’s not allowed to take tips in cash so I tipped on my cards. But he said it’s for everyone. I don’t like that but I tipped anyway.
