The service was very disappointing and the donuts actually tasted awful . The ambiance was cafe style and welcoming. Here's the specifics! Bad tasting donuts! Bad service! Very expensive for what you get! My wife, son and I visited this small establishment during our last minute student tour of Harvard University. I looked in the window on the walk by and decided to stop in and give the donuts a try. It began with a warm greeting from the man with glasses behind the counter and fresh haircut. He said hello and welcome. After waiting for another customer to complete his purchase the man behind the counter asked what I wanted. I told him and the young woman there who gave me a cross scout that I wanted a plain donut. The man's smile turned into a frown quickly. Maybe because it was a specialty donut shop which I hadn't realized. Both of the workers had their arms crossed and immediately stopped talking to us. I asked about other flavors and they both looked at me as if to say, please leave. I ordered three different donuts and the price came to almost $16z. Wow! Expensive donuts. My family and I left the store and we each began eating the donuts. We spoke about the price but felt it could be worth it if it tasted good. The donuts were not good. They looked really tasty however tasted really bad. I've actually never tasted a disgusting donut before and this was the first. The customer service was terrible and the donuts were bad. Union Square Donuts gets an "F" rating. Sorry, not many proper pictures at this time. read more

Union Square Donuts - Assorted donuts that at first appearance looked quite delicious. - Donuts Near Me - Cambridge, Massachusetts

While in Boston over the summer, I did some research on what to try food wise while in town and the Boston Cream Pie was one of the recommended items. Union Square donuts was a place recommended to try. Their donuts did not disappoint. They were tasty and fresh and lived up to the recommendation. I would definitely come back to try other donuts from here when back in town. The space itself is fairly tiny and compact. The service was quick and friendly. read more

Walked past Union Square Donuts. After lunch I encouraged my partner to circle back so we could grab one. It's a small shop, but cute. The staff was friendly and the selection was impressive. Everything looked delicious. We went with the Boston Cream donut. It was the obvious choice and didn't disappoint. If you are ever in or around Harvard Square, or in Cambridge, this is a place to go! read more

Sadly sub-par service. I was the only person there and the guy serving seemed annoyed I had entered and had disturbed him from whatever he was doing on the computer. Curt and impatient responses to my questions. Wish I hadn't tipped but I did so without thinking in order to get out of his presence. read more

It was our first time in Massachusetts so we decided to try the traditional Boston Cream donut - it was absolutely delicious with a really nice texture and a generous portion size! The staff were so lovely and service was incredibly quick Bear in mind when visiting that there is no seating area at this location, but is only a short walk from Harvard Square! read more

The variety of donuts here is impeccable. Such interesting flavors. I never order the generic stuff because they have donut flavors that i've never even heard of, which i always get and each time i do, i love them. They're fluffy and big and flavorful. Union Square Donuts is located in, well, Union Square, so it's perfect for a grab and go snack while strolling through the city. It is a fairly small donut shop so there are no tables or chairs and the donuts are on the dront display. But the location is perfect because who would rather sit in Union Square anyway. My only comment would be the staff. I've been here a few times and half the time, the staff is impatient and is not friendly. Almost like they can't wait for you to leave, which definitely ruins the experience, especially since the place is already small so you're right across from each other the entire time. read more

The donuts are really good! I'm not usually a big fan of donuts and I usually don't try other flavor besides the classic glazed but I was pleasantly surprised how nice the Vietnamese coffee donut was! The service was fast. It was not too busy when we went so we were able to order and get our donut immediately. The shop itself is a small, cute donut shop. You get to see all the donuts they have on the front display, which makes for a delicious and nice display read more

I had a great really great experience here today! I was originally attracted by their collection of fall-flavored donuts: Apple cider cake, pumpkin cream bar, pumpkin spice latte, and apple ginger! A lot of them also have vegan versions. I finally went there today to treat myself. The service was really good! Although it was a small grab and go place in Harvard square, the server greeted me warmly (I wish I've asked their name!). They recommended according to different flavors and textures (cake-based and yeast-based) to me patiently. And I ended up having "caramel pumpkin cheesecake" donut since it looked the most appealing and it has cheesecake filling. Since I was about to travel out of town and worried that these seasonal flavors will be leaving so I asked if they will be available next week--- turns out that many flavors are leaving tomorrow! I also really appreciate the server here who nicely checked their notebook and pointed out which flavors are leaving while others are not. And now comes to the tasting time!! It is a really eye-opening experience. The donut dough is so fluffy and soft. It's not over sweet at all. And compare to other chain-branded donut, they don't have that metal-chemical flavor that you know is overdosed to raise the dough. What's more, you can see the vanilla bean in the donut dough which proves a solid quality! The pumpkin cheesecake filling--- surprisingly creamy, rich, and tastes exactly like pumpkin pie but lighter/airier. I also appreciate the nutmeg and cinnamon flavor that stood out. The caramel outside is nicely covered and add pleasant sweetness. The donut is topped with gingersnap cookie crumble, tasting like a fancy version of pumpkin pie crust--- which makes the donut like a decomposed/reorganized pumpkin pie! I paired it with coffee but honestly the donut is not over sweet at all that you will not be overwhelmed even eating itself as breakie. All in all, I am totally fall in love with this donut shop! (Oh there is a discount if you are Harvard affiliated!) I would recommend if you wanna treat yourself with decent dessert while feel good about eating it (not-so-guilty because of the good stuff and reasonable sugar content!) I will definitely come back!! read more

One of my top donut shops. They have fun trendy flavors that cater to any taste. I got the cinnamon sugar donut and it was soft, super fluffy, and delicious. Not overly sweet, and not too bland. I finished it hours later and tasted just as perfect. They also have some of the best coffee I've tasted in Cambridge. The shop is small with not much seating, but super cute. Overall 10/10 and would love to try more flavors. read more

Their glazed donut on Sunday morning is not good if you like mom and pop donut shops. I do know about the clientele that like 5 dollars donuts. I have them 4 stars because I realize everyone is not the same. And maybe an 11 am Sunday morning donut is not a fair judge of their quality. But if it is equally to thier best quality then I would give it a 2 Star. read more

If you're into artisan donuts, you will love Union Sq. Donuts. I had to try their Boston cream donut and it was delicious. I really enjoyed it. It was very similar to the Boston cream donut I had at Blackbird Doughnuts. Nice to have this as an addition to Harvard Sq. I will be back to try more flavors. read more

ordered off UberEats gave me the wrong order. didn't even tell me they were out of what i purchased. gave me something else instead. terrible service read more

I was excited to try these donuts as I had heard so much about them and was missing a good donut shop. However, for the price of the donut, which is typically $4-5/donut, it's just not worth it. The donuts are quite large which helps justify the price but the ratio of dough is too much and it's extremely dense. The pumpkin spice latte donut was the best one out of the 4 types I ordered. That one tasted the freshest and was nice and chewy. Overall, it's a decent donut, but if I want one in the future I'll save my money and go to Dunkin which is honestly better. read more

I enjoyed my ricotta pie doughnut, a temporary offering, and hubby's vegan coconut doughnut. Both were delicious. Hubby says he prefers a harder, more cakey doughnut, but that's just not the style here. The cashier was pleasant. read more

Best donut I've ever had! Workers are friendly. You won't regret going to this place!

I've been a regular since their soft opening a few months ago, and I have to say this is one of my favorite spots in Harvard Square! The chai latte is one of the best I've had in the area (super good with pumpkin spice syrup), and the donuts are of great quality! My personal favorites have been the rugelach sufganiyah, pumpkin pie, and oreo cheesecake. I also personally like the vegan options, which I go to when I want a lighter donut. Finally, the service is absolutely great, as the employees are super friendly and helpful when giving recommendations. read more
