Amazing bagels so soft and delicious. Service is fast and the place is nice and cozy. The donuts are truly amazing, and the bagels are consistently so good! I love that they are open 24/7, which makes this the perfect spot for any late-night cravings or a quick morning treat. Highly recommend stopping by if you are in the area. read more

Food always fresh my go to is the V-8 with the jalapeño bagel. Our family of five casually stops by when we are working nearby and our total comes out to 60+ dollars, so keep in mind that it's expensive but you are paying for quality and that's something that I can do occasionally and happily at this location. read more

Awesome donut place that's open 24/7. I ordered the Cronut Holes & a strawberry french cruller. The cronut holes had the perfect crunch & glaze while the french cruller was nice and soft. Definitely the go-to spot for donuts if I'm in the area. read more

Donuts: 4.1 Service: 4.2 friendly & patience Needed a snack while my wife was at her facial appointment. So while sitting in the car, I decided to walk around the area for my snack but right across the way was SK Donuts. So off I go... Walking in, it's an old school vibe that serves more than just donuts. They have a huge variety of donuts to choose from; I was like a little kid again wanted to push my face against the glass counter (but couldn't since I'm over 6ft tall these days). After taking it all in, I opted for a dozen of their Cronut holes and 1/2 dozen of regular donut holes for my wife so we can portion out the carbs, LOL. Their cronuts are delicious and addictive! Soft and sweet (maybe just a little bit too sweet for my taste). The cronuts peel off like a croissant but has a nice chew like a donut. And the donut holes are soft and sweet with the right amount of chewiness like a regular raised donut even though they're bite sized. Looking forward to our next visit and our next donut here... read more

Plenty of parking. Pricey. Almost $4 for a Cronuts. Old Lady at the front was mean, pissed off or something. As for the cronuts - chocolate toppings were too sweet. I literally can't taste chocolate except the overly sweet brown stuff. It was too dense, so doughy, heavier than a regular donut. Custard fillings were yummy though. read more

Are Cronuts still popular? The only other bakery I've see have Cronuts is Paris Baguette. I decided to get 1/2 dozen of Cronuts for $4.50. There's 2 kinds: cinnamon sugar and glazed. It was ok. Best eaten fresh. They offer many options for donuts and they are open 24/7 for your late night munchies. read more

Stopped by on a whim and remembered that they sell cronuts. It's was around 2:30 and they had a bunch of donuts. I got cronut holes (6 pieces). It was yummy, not too sweet & was fresh (not hard and crumbly) I saw that they are opened 24/7. Prices are decent. They sell sandwiches, mostly breakfast style. The woman working behind the counter was friendly and polite. read more

Best local spot open 24/7 for donuts! I have been going here for years and my dad actually put me on because he had been going here for years as well! I believe it's family owned and the Donuts always taste fresh and soft somehow some way. I came at 11PM and they were deep cleaning the outside and sweeping the inside, but the case of doughnuts was full. I was half expecting the donuts to be hard and stale since it's the end of the night but I bought a half dozen, went home, bit into it and was amazed - 10/10 doughnut. Highly recommend stopping by here, literally anytime you're in the area and craving a donut. read more

A sweet tooth & donut lover's paradise! Came here as per my boyfriend's recommendation of the filled cronut. I enjoyed the custard filled cronut. Texturally these things were amazing. Lightly crispy with a luscious sweet cream. The jam filled ones weren't my favorite, as I thought the jam itself tasted a little ketchup-y. These cronuts are definitely in the sweet since they're coated in a sugar glaze. As someone who isn't the biggest sweet tooth, I wish they sold a version without the glaze. There was a small line when we went which went by quickly. Prices are super reasonable & it's convenient that they're open 24/7. Place itself looks very hole-in-the-wall and outdated. I have a feeling this spot is here to stay. read more

Some dude on Instagram sent us there based on his filled cronut holes review. We got both the custard and jelly. They are pretty good, bumping up to great (but not life-changing) after a visit to the air fryer. By the way, this isn't a "need to come early" place- they know they are in demand, so the keep making fresh ones. The plump apple fritter was tasty though a little greasy. My wife got a stomach ache from the old-fashioned (both original and maple), which I enjoyed. I mean, I enjoyed the donuts, not the fact that she got a stomach ache. Four star donuts, but an extra star for their service, which is fast to accommodate the line that snakes inside the store and out, the selection of meaty breakfast sandwich bagels that looked really good, no card surcharge, and the fact that they're open 24/7. read more

Craving donuts after visiting the Don Edward's wildlife refuge. Sk did not disappoint! Open 24/7. We got there at 3 pm. Donuts were fresh! Love that there is seating inside and out. We got a chocolate twist, maple old fashion, and cronut holes. All the donuts were so tasty! The cronut holes were mind blowing. Highly suggest these. I also got the Vietnamese iced coffee. It had a deep coffee flavor and was perfectly sweet. So good! Highly recommend this place. read more

Love how this place is open 24-7. Came in to pick up some of the Custard-Filled Cronut Holes. The crusted is very light and not too sweet at all. It is one of the best I have had!!! Picked up a sausage, bacon, and egg sandwich in a croisannt, not the best I have had but still good. Just like any other breakfast sandwiches. I would differently return for their donuts and the Custard-Filled Cronut Holes. They were pretty quick on making the breakfast sandwich. read more

Came to SK donuts the other day and boy their stuff is FRESH! I didn't think much when I came in until I had their maple flavored donut. The texture was not hard and the maple is freshly glazed. The size is just like how you remember it growing up and I love it. It won't blow a hole in your pocket grabbing one of these, come and check it out. I'm giving it a 5 out of 5 and I will definitely come back when my cravings for donuts come again! read more

Eat here if you love BUGS! I ordered a tea iced tea and found a fly in my drink. I went back to tell them and show them the fly and they had the audacity to tell me I put it in there myself! Yes, I'd totally put a fly in my drink on purpose. I was refused a refund or remake and when I asked for a manager I was told she (KIM) didn't know her name and was playing dumb the entire time. A terrible, low life place with no customer service values. If I could give them 0 stars I would. read more

Worst customer service and bad hygiene I will never ever go there again instead go down this road there is a place called fresh donuts. I'll be using them from now on. Also, I had a coffee from there and I have a stomach issue with milk. I only drink regular milk with my coffee and it's clear they have regular milk on the fridge and I can see it and they didn't let me use it and they told me to take half and half and half half-and I can't consume that to heavy my stomach and will cause me issues. read more

Great donut shop. Open 24/7, lots of parking, seating inside and outside, and friendly staff. I got the chocolate and glaze cronut, I wanted maple but they had no more the chocolate and glaze were super good so I couldn't even be sad about it. I also got Vietnamese iced coffee, actually liquid crack, tasted so good and had me pumped up the whole day. Looks like any regular donut shop and I love that it operates 24/7! read more

SK Donuts - Maple and glaze cronut Vietnamese coffee - Donuts Near Me - Union City, California

I was randomly craving donuts and stopped by SK Donut on my way home after years of driving past it. I was greeted by the sight of a huge display of fresh donuts, and noticed that it was quite a small place. But there are a few tables inside that can seat 3-4 people each if you'd like to sit to enjoy your donuts. Ultimately I decided to go with an apple fritter and cinnamon crumb donut. The cinnamon donut was light and sweet, didn't feel too heavy at all. The apple fritter was one of the best I've had. I also ordered a Vietnamese coffee and thought it paired perfectly with my donut; not too sweet and not too strong. I can't remember the prices exactly but I do remember being so impressed by how affordable they were. I think the cinnamon was $2 and apple fritter was $3.50. Such a great deal especially because the apple fritter is huge and you could definitely split it with another person. I can't see myself going to Krispy Kreme again after this and would rather support this nice local family-owned business. Crazy that they're open 24/7 too. read more

Always open - love their donut holes ($3/dozen) and cronut holes ($8/dozen). They have other specialty donuts like fruity pebbles and old fashioned, as well as savory food and drinks like Vietnamese iced coffee. As I like eating more bite sized things, their donut holes are best for me and always a 5/5 for both. This time especially it tasted super fresh and airy for both. It took about a minute for them to get both dozens in their own baggies. To be fair, I only got donuts. It's a donut shop and exactly the ambience you would expect. You can tell it's a local favorite as people stop by and chill there and the hours are accommodating. read more

SK Donuts - Dozen Cronut holes - Donuts Near Me - Union City, California

The creamed filled mini cronuts are a must here. Filled fresh when ordered. $10 for a dozen but decent size. The custard isn't too sweet and the cronuts are fresh and taste good if you eat them the first day. They get soggy the next day and the outside glaze melts off. Glazed cruller was mid. Prices are a bit high for pink box donuts. I like that they are open 24 hours. Service was ok since whoever was working was not very friendly. She was a bit short and rude. I try asking a question regarding the custard donut holes vs cronuts and she seemed annoyed. read more

Just a quick update! We were again at Huong Sandwiches (they did a rename recently and a price increase eek!) so we were curious to see if SK Donuts had their apple fritter as we were influenced by TikTok. Parking here is pretty plentiful so it doesn't feel like we've ever struggled finding a spot. So we dropped by but it was the end of their day and they sold out probably because of their new found fame on TikTok. But still well warranted and glad they're getting more and more foot traffic so that they get their other donuts some love as they've been here for years/decades even. It's your typical donut shop look and feel. You know? Like they had a template for donut shops back in the day and just did that over and over again. So you see all the donuts and they have seats that line the outside of the space. Though we didn't end up getting our donuts, it's still a great donut shop. Definitely drop by and get some donuts, donut holes, and cronut holes! read more

Came here late night Saturday. One of my gym girlfriends sent me here when I asked her where she got the breakfast sandwiches from our potluck. The sandwich was bomb and perfectly portion size!! My friend got the maple donut which she really enjoyed. I wanted to try the mini filled cronuts, I tried both the jelly filled and the custard. I think the custard was good, but it needed more vanilla it was light in flavor otherwise good! I am very bias and love a good jelly filled donuts and this was it! The cronut was nice and flakey and the jelly was delicious! read more

I have to say this is one of my new fave donut spot along I-880! I don't get them often but when the crave hits, SK Donut & Cronuts hit the spot When it comes to donuts, I stick with the classics and seek a simple glazed, apple fritter, and if you have a maple glazed I'm good...so if you have a variation like a cronut, custard donut holes or one with bacon even better! Sadly, they don't offer one. Soft, fluffy and not overly sweet! Service friendly, quick and efficient. Nothing fancy about this spot. Plenty of seats for enjoying your breakfast croissant or donut with coffee. Line forms by 9am on weekends. Sign notes open 24/7. read more

4.5 STARS Date: Sunday, February 9th, 2025 Time: around 3pm *Donut Holes *Cronut Holes For the super bowl, a friend of ours brought donuts and cronut holes. I had never heard of a cronut hole, so I was intrigued. Not gonna lie, they aren't the prettiest pastries. Idk why they reminded me of worms. But they are mighty tasty - flaky, chewy, buttery. The reg donut holes were good as well. And with them being more or less bite sized, it's good for sharing. Glad I was able to try this spot. I am now a cronut hole fan. REVIEW #3694 read more

We mainly came for the convenience since this place is open 24/7. We were surprised by the selection considering we came at 1am. It definitely hit the spot for a late night sweet craving. My favorite is the glazed cronut. Their breakfast sandwiches are also good but nothing special. The service is fast. There is seating but it seems like a grab and go type of place. There is also a lot of parking in the plaza. read more

Ok we came here on a whim. We wanted custard donuts and saw this place on yelp. We came in on a Friday afternoon and the lady who helped us really nice and quick. We ordered the Vietnamese coffee and the cronut hole filling with custard. The coffee was delicious and not too sweet. The cronut hole fillings were better than expected. She filled them right then and there so the cronut was nice and crispy and flaky while the freshly filled custard was creamy. A line quickly formed but it moved quickly. They are open 24/7 which mind boggles me as most mom and pop donut stores that I know of are closed by 2 pm. This is located in a plaza with plenty of parking. I didn't see any public restrooms. Would like to come back and try their breakfast sandwiches next time read more
