    Union Square Donuts never disappoints - but this location can definitely get really busy. We went right when it opened around 7AM and there were already 5 people in line. The donuts are fresh, creative, and absolutely delicious, with the perfect balance of flavors and textures (fried brioche, filled and not filled, but also cake donuts). We got some of their season flavors (blueberry pancake was a favorite) but our all time favorite is the Boston Creme, which they fill quite well so it makes the price worth it.

    Been saying this for years and after yet another annoying morning of having the lid just pop right off my coffee - I will say it again until my gift card runs out - GET BETTER LIDS. Find one brand that works great and stick with it or something. Can't get a coffee for a morning walk bc it drips out the side of the lid and I'm walking with espresso dripping on my hand the whole time which is gross and annoying. Can't even depend on it not to drip down the side in the cup holder on my car's console. And I'm tired of it popping off and losing a coffee at least every 1 in 7. Not to mention the stains on my jeans or shoes bc who would even expect that to happen? It's quite something when I come into work and why I have coffee splatters on the shin of my denims then say, oh you got USD today? I don't come here for donuts. Only caffeine. And after five plus years of annoyance .. GET BETTER LIDS PLEASE.

    The spot was very clean and the staff provided excellent service. The donuts had creative names and looked appealing, but the taste didn't quite live up to the presentation. Not bad, just not as delish as I expected.

    Dubai Chocolate Bar

    Had to come back to update my review! Dubai Chocolate donut is the best donut in my opinion and It's probably the longest reigning special promo donut. I've been buying one each week as a "just-in-case they discontinue it without warning" because sometimes they'll announce the end the date of their donuts and sometimes you get a "new flavor alert" post and you're not sure which one they're replacing till you check their menu. Here are more added to my fave list since my last review: Oatmeal cream pie - this is a must have whenever they release it Baklava - I haven't seen this one since 2022 but hope it comes back Red velvet - this is usually around valentines. Really good fresh They had a pistachio halva donut which I didn't get to try in time but my friend did and she said it reminded her of Sarma which is a pretty a big deal!

    My first time here and I got the donut holes and cinnamon roll. Next time I would try something different. The donut holes tasted stale. The items looked better than what it tasted like. The location was great in Assembly row with plenty to do in the area. Service was mediocre. The facility was well kept and aesthetic.

    My husband found this donut shop and surprised me with it on Mother's Day. Cute little place with some great flavors and great looking donuts. Here's what I got: 1. Strawberry daiquiri- man do I love a strawberry donut! This one had a great flavor and it was quite pretty. What I didn't like was the edges of frosting rolled in sugar crystals like an alcoholic beverage. I get the idea but this made the donut experience very crunchy and I was not a fan of that. 2. Sea Salt Whiskey- lite in flavor. I would have liked a bigger flavor punch. 3. Cannoli- WINNER! By far! This is the second time I have had a cannoli donut and this donut was WAY better than the one I had elsewhere. The cannoli filling inside was just a perfect balance of the outside softness of the donut with small hints of chocolate. Matcha drink was just like any other matcha drink. True score: 3.5 But the true score of the cannoli donut: 4.75

    Had a good experience. The young ladies behind the counter made great recommendations when I couldn't choose from the beautiful selection of donuts. It was nice and clean in the spot with lots of treats and drinks. Glad I visited during my short stay in Boston

    Chocolate covered donut was amazing. Maybe best ever. Quick service, no line on a Saturday afternoon. I was not as in love with the raspberry filled donut. The donut itself was excellent- light and good flavor. It had a lot of filing and it was jam, so it was heavy. It's a preference thing for me- I like jelly. Yah, caught me- I am a dunk's jelly donut fan. If it had jelly inside it possible it would have been best jelly donut ever. This place is worth the calories if you love donuts.

    These donuts were delicious! However, I think they were comparable to other donuts i've had. We placed an order for pick-up, and like how you can pick up anytime. The workers were friendly, and it was pretty busy when we stopped by. A nice spot to get a sweet treat!

    The shop was clean and the service was good. Everyone was friendly and welcoming. The donuts had some cool names and looked pretty good, but honestly, the taste didn't match the hype. They weren't terrible, just not as flavorful as I expected.

    This was SUCH a good donut. We were wandering around the market and had to stop once we saw this stand. The Salted Brown Butter Cruller was a great mix of sweet and salty. The texture was nice and soft on the outside but still had a harder exterior with the glaze. Service was super quick as there was no one in line. Give this a place a try right now!!

    Brown butter hazelnut crunch
    Hannah L.

    I asked for the most popular donut here, which they said was the Brown Butter Hazelnut Crunch. It looked beautiful, along with the rest of the donuts in the display case. Glossy, lots of glaze and hazelnut topping. I was excited to take a bite, but once I did it sort of just... fell flat. The donut tasted greasy and stale, like it had been sitting there for a while, which was weird because this was in the morning and one of their most popular items. There wasn't much flavor beyond oil, which is not how a good donut should taste. The texture was dense and chewy. Would not recommend.

    Stumbled upon Blackbird Doughnuts as they were in the only building we could find with a public…read morerestroom. I am glad we stopped in because it led us to find these incredible doughnuts. I asked the employee working if they were a chain and she explained they are a chain local to Boston. She also shared the doughnuts are made fresh every morning. They had a display case with the donuts featured and they sure looked great. We were pleased to find the actual donuts looked even better than the display! Both of our donuts were huge and the frosting/filling proportions were generous. The menu consists of classics and then a featured monthly selection. I picked a classic doughnut: chocolate sprinkle. My husband went with a may selection: cherry jam Bismarck. We both loved our selections. My husband said cherry filling is rare and the flavor was spot on. To be honest my only regret after how delicious we found the donuts to be is not getting more.

    Really good place for donuts, coffee and breakfast…read more Sometimes there is a line, and you will have to wait a little bit for your food. They open at 8 AM, but they don't necessarily have everything ready at 8 AM sharp, so you will have to wait. If you are in a rush, better off go to another place nearby that opens earlier and get out of the door.
