★★★★★ 5.0 Walter Zarenko · Nov 2025

I’m shocked chagrined horrified and stupefied that anyone is giving this place under 5 stars. These are the best donuts around! We have got a few donuts here four different times. They have inventive varieties with complex flavor profiles which are not overly sweet which is great. The pecan pie donut was one of the best donuts I’ve ever had. Boston cream was dynamite too. You need to eat them within a day or they aren’t as good. So glad they came to town and they are comparable to Kane’s.10 stars out of 5

It sounds like I am the odd man out in looking at others’ reviews, however, I am a huge fan of Union Square Donuts and am so pleased it is at Market Street. As someone who loves donuts, and often seeks out donuts from a variety of stores, Union Sq has consistently been one of my top choices because of their unique flavors, consistent bakes, Vegan options, high quality coffee from Atomic, and friendly services. Is it expensive? Sure! Is it a small store? Totally (if you think this one is small do not go to the Harvard Square location 😉). But since when did a couple bucks, unique flavors and a small store space get in the way of eating a donut? Life’s too short people! Can’t wait to return and love that I don’t need to drive into Boston to get my fix anymore.

Tried a few of these out with family, as a group we didn’t like any/most of the ones we tried. They look nice but high prices for the taste. I wouldn’t recommend or go again.

Sure, it’s a small “pop-up” as other have noted. That’s not the point, they’re not here for a walk-in, sit down, and lounge while you drink coffee and eat one of their donuts. They’ve got a wide variety of selections, both for those with and without dairy allergies. That alone is hard to find. Add to that that both offerings are amazing in proportion and taste makes it even harder to find. Ignore the negative reviews, take a chance and you’ll be happy you went.
