Union Square Donuts offers a wide variety of treats for the sweet tooth out there. I tried a couple different ones and they all tasted good - although by the time I tried them they weren't so "fresh". Their coffee was great. Service was good and the place has seating available.

I recently visited Union Square Donuts at Assembly Row and I can’t recommend this place enough! As a Canadian visiting Boston, this was my second time here, and I’m already looking forward to my next visit.The donuts are incredibly fresh, and the variety of flavors is delightful. Every bite is a treat! The service is also outstanding; the staff is warm and welcoming and always patient if you have questionsHaving tried many donut shops, I can confidently say that Union Square is one of my favorites. I highly encourage anyone to check it out—you won’t be disappointed!
Oct 2 · Yannick XXXI used to work in a sub shop in the early 80 and I remember this place in union square. Fast forward my wife bought few donuts from this place few days ago. Let me tell this, I had the blueberry donut. It was one the best donuts I ever had. I can still tasted in my mouth and I can’t wait to go back and try more donuts. Thank you very much.
May 30 · Tahany SadeddinLove your doughnuts. But my last visit on 7/13/25 I was incredibly disappointed in the overall cleanliness. Poor air quality. Didnt smell clean and the the restroom was horrific. Poop on the seat. And they were not busy, so the bathrooms should always be clean for customers. So based upon your rude reply I will gladly take my busy elsewhere. And you clearly ignored the rest of my comment Your staff members reflect your managing of this location. The place wasn't clean and the staff should be on top of that. You can't handle a negative review. Do better next time. And I'm glad I left this review because poop on a toilet seat is unacceptable. And your staff should be monitoring the cleanliness of the restrooms for it's customers.😉 It's just common sense,
Jul 22 · Emily HoneycuttLoved the cream filling, loved the bottom half of donut. Top half was bit bitter. Maybe it’s an acquired taste. Donuts are priced little on higher side. Would love to try different donut but cannot come frequently because of price.
