You’d think by using the app and doing a mobile order they would be less likely to mess up but they still do. Whole order was messed up including some wrong items and missing items. This store is going downhill fast, I’ll take my business next door to Starbucks next time.

One of the slowest dunkins I have ever been to. Average of about 15min in drivethru on multiple occasions. Employees don't say the absolute minimum or nothing at the window. Regularly forget items. Trash is never emptied, it's disgusting.

Stopped for 2 coffees tonight. Nobody in drive thru. Took 5 min for someone to take order, then get to window, girl looking out, talking and laughing with the guy working. Not a care that 4 more cars were behind me. Was at window another 5 min before I just drove off. Will never stop here again! Went up street to the dunkin donuts.and got our order pronto and with a polite gentleman. With those 2 employees, its a matter of time....you wont have a business!

Ordered through the app and pulled through the drive thru. There were no cars in the lot and one person in drive thru. Orders weren't complicated. Gave me an everything bagel sandwich instead of croissant. It clearly says croissant on the bag. Mistakes happen I know and I worked at a Dunkin when I was 18 but I mean.. c'mon now. Have a little care. It's not like they were overrun with customers or something. I'm not sure how they messed it up other than just a lack of caring. This is my lil Sunday treat and it's not really a great treat when I get a sandwich I find to be considerably less enjoyable. Coffee was good at least. Please pay more attention to what you're doing. Girl at the window seemed confused about whether it was a mobile order, then had the wrong order number and was confused about whether we were waiting for more after getting coffees. I don't eat out much and this will honestly probably cause me to choose a different location, possibly even a non-Dunkin, in the future.

Loved the privacy of the layout and the few customers present at the same time I was there with my BFF. Such a nice place to meet with my friend and enjoy the wonderfully delicious drinks!
