Not much to say...Donuts are fresh and delicious; price is very reasonable. It's located in the same vicinity as Albertsons', parking is always available. My go-to is Apple Fritter-crusty outside, soft and apple bites inside. Service is excellent, very friendly. read more

Rainbow Donuts is the closest donut shop to our house. They usually have my and my kids favorites. We get a 1/2 dozen and it's $10. The ones that we normally get are: Glazed Twist, Chocolate Glazed, Rainbow Sprinkles over white or chocolate cake, Chocolate Bar, or Chocolate Sprinkles. All are very good and a good size for the money. Give Rainbow Donuts a try and I think they'll win you over! Please see my photos! Xie Xie! read more

Rainbow Donuts - Ham, cheese and jalapeño croissant! 10/10 - Donuts Near Me - Diamond Bar, California

Date of visit: November 22, 2024 I've always been a sucker for a good apple fritter, and I'd been curious to try Rainbow Donuts' version seeing how I pass them every time I visit my fiancee's neighborhood. A couple of weekends ago I finally had the chance. For $3.50, I got a very large apple fritter with a free donut hole thrown in. Much more expensive than what I normally pay for at my local donut stores in San Diego... but I ended up splitting the fritter in two due to its size, and each half made for a delicious part of my breakfast over two days. Plus, that donut hole was also pretty good; might have to get a few more of these on future visits. I was taken aback a bit at how small Rainbow Donuts is on the inside, but the service is nice and as I left, several other customers were coming in. I can see myself coming back to try more of the donuts offered. read more

The lady working here is so kind and the Vietnamese coffee is so good !! I usually get the breakfast sandwich as well and that is also delicious. I was able to try the donut holes and Omg they are a must . This place truly is awesome read more

I've probably been coming to this donut shop for over 20 years now. Sad to know that the previous long time owner sold the store a couple years ago, but just want to mention that he and his family were always kind and super friendly. Always enjoyed the quality of donuts here as well as my kids who grew up on these. Ordered half a dozen today and had to get my old fashioned maple. So so good. The new owner threw in some donut holes to fill in the gaps in the box. Ok, I think we can be friends. read more

Good variety of donuts! They still had a lot left when I visited on a Friday at 5pm. They close at 6pm, which makes me wonder if they use the leftovers for the following morning. Your regular basic donuts are $1.75. Can't believe donuts are so pricey now! I also got an Apple Fritter, which comes in two sizes. The smaller one was $2.50 and the larger one was $3.50. I thought both the sugar twist and apple fritter were good! Not too oily. I do want to try their original glazed donuts next time. Given they still had so much donuts close to closing time, I wished they offered a deal to clean up the place (unless they really do resell them the next morning). read more

Rainbow Donuts is hands down, my absolutely favorite donut shop. I love them!! They are family owned and their donuts are fresh and delicious every day! I love them so much I took 3 dozen to my dad's 70th surprise birthday party as an added dessert next to the cake!! They were GONE by the end of the night! If you are in Diamond Bar GO THERE!! read more

i love the donuts here! they have the style i like which is yeast or raised type of dough. these are much fluffier and easier to eat than cake donuts. other than the buttermilk old fashioned, i haven't tried their other cake ones because i always just go for the chocolate, sugar & glazed twist or circle donuts, maple bar, and apple fritter. the old fashioned buttermilk is great and buttery here. it's not dry like many other shops. the owner seems very nice. i've never had bad service here. it's your simple donut shop with the mom and pop feel. this is your friendly no fuss local donut shop. read more

Shop owners are very friendly and nice. They have this chocolate chip donut that is so good. It's covered with chocolate chips on top and has a layer of chocolate in the middle. So decadent. I expected it to be too sweet but it was perfect. I also tried the blueberry glazed donut which was also yummy. Again, not overly sweet. Glad I discovered this place! read more

Super cheap mom and pop donut shop! Only $5 for a Blueberry glazed old fashioned donut ($1.75), sprinkled donut ($1.5), and half dozen donut holes ($1.75)! + Blueberry glazed old fashioned donut ($1.75): strong artificial blueberry flavor and a bit too sweet for my liking. (6/10) + Donut holes: very plump, fluffy, and airy! She threw in an extra one for me too :) Loved being able to quickly stop and pick up some donuts on the go! Would definitely return to try other donuts. read more

Thank you Lynn for Excellent Customer Service taken all my 8 dozen donuts to be prepared for Friday March 1 st for my son funeral. Thank you Pin & Phiek owners, partners, husband & wife all made sure all the donuts orders prepared perfectly. Not mashed up together or squash. Prepared nicely on big white boxes. Excellent presentation to all our family & friends. Was so fluffy like, how my son Shawn loved. Inflation increased what we remember prices but still yummy & delicious. We just call prior to ordering to be prepared how much we're ordering, so enough to get the selections all the selections we wanted to serve. Thank you again Lynn , Pin & Phiek for caring. read more

The cashier there tried to get extra money from me charging me extra for my brothers donuts, took the box away and walked us out the door! I couldn't believe it after I paid for it aswell. I don't even know what to do to get my money back! read more

I wanted to pay together not separate so I don't get charge the .75 cents twice lied to me when I paid the first time telling me it's was all one perchance than tried to get that extra .75 from me. I don't like shady people and this made me feel uneasy. read more

I was driving by on my way to work and decided to stop by to give this place a try. They have a small case of donuts with a little bit of everything. They had a few left of my favorite type of donut, the buttermilk. I also asked about a unique looking old fashion donut and she said it was blueberry flavor, so I decided to get that too. I also decided to pick up a generous sized ham, cheese and jalapeño croissant for my son. He hasn't tried the croissant yet, but I ate a bite of both donuts and was impressed with both! Donuts are fresh and decent sized, but if you're looking for something bigger, They also have a huge cinnamon roll and chocolate chip donut. I'll definitely be back to try more! They also make croissant sandwiches and they look yummy as well! read more

I used to live in Diamond Bar as a kid and I remember that this donut shop was always in business for as long as I can remember. Now, as an adult, it warms my heart to see that business is still doing well. Recently, I've been finding myself making a stop here during the morning before I head out to work. My go-to items are their breakfast bagel sandwiches and iced coffees. The food comes out hot and fresh, and service is great too. It's a Mom 'n Pop type of small business so I'm always glad to support them even during these tough times of inflation. read more

I LOVE the iced coffee here. Obsessed with it! I come in every morning for my Vanilla Iced Coffee. Once in a while I'll add a ham & cheese croissant (which is amazing) or a donut. The husband and wife who own the place are absolutely delightful. They are so so so nice and happy, it makes a happy start to your day. There are also some very nice older veteran men who are regulars here who say good morning when you walk in. So nice! read more

I have not yet tried their donuts. My review is based solely on their surcharges. $0.79 for any card purchase and $2 for anything $36 and over. A dozen regular donuts is $18 so if you order two dozen donuts, you're automatically charged $2. Bring cash if you want to avoid the surcharges. I'm all for supporting small business, but I don't know about charging customers more when they're already helping the business with their larger purchases. hope their donuts are worth the surcharge. read more

EXPIRED MILK Even though I moved I always try to get a donut here when I'm back in town. Today will be my last- they sold me expired milk! It tastes funny and I checked the date Dec 18 ... today is the 20th gross. Charged me .75 to use my debit card too. They usually throw in some donut holes for free but nothing from the lady not even a smile. Turns out Tom no longer owns it and it shows. Donuts are still delicious. Just make sure you check the milk expiration date! read more

Seriously the best donuts in Diamond Bar!!! Been coming to this place since we moved here! They always have a donut for everyone no matter what time you go So we decided to go through Rainbow for our baby sprinkle we had a week ago!! Their custom donuts exceeded our expectations, they were so sweet and easy to work with. We took in our invitation and we discussed the 3 dozen we wanted to order. Pricing was absolutely perfect and we didn't feel overcharged at all!! We will be coming back for more custom and our regular donuts always!! thank you again! read more

Donuts grease sponges with extra sugar please! You sometimes just want one of these delicious breakfast treats so it was a random Sunday morning trip with the coworkers to get some of what's good! Upon arrival we were delighted to see that they still had a good amount of the dough goodies left for it being about 9:40 on a Sunday once I glanced around at what was yummy I came to the conclusion that I needed a apple fritter and one of those totally yummy old fashioned blueberry ones which I was like oh so much all about after the first bite! The blueberry old fashioned was delicious I don't think I've ever had blueberry in one of these before and it was definitely one of the better donuts here by far so much so that I'm definitely getting one of these again at some point as oh soo yummy! The Apple fritter was about average as to what it should be and pretty much standard to the ones you find at other shops it was in itself yummy with the crispy edges just how it should be! Overall with some milk to wash it all down this is a decent donut shop that's making what's good and I'm sure we will venture here again at one point when the coworkers and I are craving that greasy breakfast goodness! read more

favorite donut place, really nice people, customer friendly, pretty expensive but that doesn't matter because I'm poor anyways,

I came in last week at 2pm on my lunch to get the turkey croissant the lady working told me she cleaned the machine already so she wasn't going to make me the sandwich, which doesn't make sense since they close at 3pm. Today I came in the morning and ordered a donut and turkey croissant. The lady said she was alone and had to help the five people behind me before she could make my sandwich I said ok I went outside came back in because I left my donut on the counter. I see two lady's behind the counter now , one just watching the other make my sandwich. I said excuse me 3 times before they acknowledged me. It's very rude when they could hear me. I am very displeased in the customer service both times I came, I will not be back . read more

Great family owned donut shop! Always so friendly and all treats taste amazing!! Would definitely recommend!
