Great value for excellent quality! Recommended eating? Everything!! Highlights? Crunchy, sweet, perfectly textured freshness of the apple fritters blows Dunkin' Donuts out of the water. The ham and cheese croissant doesn't skimp on the filling - satisfying for one but easily shareable. Donut holes are light and airy... Friendly service with a smile and it is readily apparent there is joy in their craft. Highly recommended for a delicious diet-busting splurge well worth the calories! read more

I use to come here all the time then left for a while and came in for boxes of donuts. I think it's now under new management because the service was not the same. I was so happy to return and was disappointed. Also the $.75 to pay with a credit card was a major turn off. I don't like doing business with companies that charge you to use a credit card. Won't be coming back. read more

I can tell they are using the quality materials for the donuts. I am quite picky about the texture of the donut, but I would give to Rainbow Donut! I would definitely recommended this store to all my colleagues and friends!!!!!!! And the service is a plus too. The lady in the front is super nice and friendly!!!! read more

Not a fan of this donut shop. The interior looks extremely run down and NOT clean. The donuts were quite dry and for some reason tasted stale. I went in around 5:45 PM After calling ahead for lemon donuts. When inside, the lady behind the cashier kept trying to get me to buy extra donuts after I clearly expressed not wanting anymore. She put them into bags and tried to get me to pay for it, I refused and she eventually put them back. Not a fan. Donuts do not taste fresh and after walking in, you'll lose your appetite if you decide to look up at the ceiling with spiderwebs and dusty counters. read more

Best donuts shop in Diamond Bar, they are so fresh and delicious I highly recommend this place

When I need a sugar fix I love getting some donuts here. Lots of great flavors and straight out of the oven. Always nice and warm. My go to donuts are the blueberry old fashion, the original glaze and the chocolate with nuts. The dought is nice and soft. Each bite is heavenly. Can't get enough. read more

My first time getting these donuts was after quarantine started and I had them delivered in the morning. The donuts were very soft and freshly made! Their glazed donut is very large in size and the flavor is amazing; it's not too sweet. Definitely will be trying out some other flavors in the future!! read more

What a rude lady working there. We came in for a few doughnuts and she was asking rude questions that were none of her business. She said do I work and my wife stays home and I just give her money. It's ironic that she would mention this when she works herself in a highly skilled job selling doughnuts, read more

Wow! My husband brought home these donuts home and they were huge! The box didn't even close. They were definitely a treat. Our kids loved the sprinkled donuts. The chocolate glazed were yummy and didn't melt like some other places. The sugar donuts were delicious. I'm a sucker for a crumb donut and theirs was so good! They were good the next day too! You get a lot for your buck when you get your donuts from here! read more

They have the most delicious donuts! Everyone I've brought them to loves them. Downside is that they are a little pricy, $1.75 for an old fashioned. Bring cash, they charge 75 cents to use a card. These donuts are seriously delicious! read more

First and last time at Rainbow Donuts!!! I ordered four different donuts. They were thrown in a bag with napkins smashed on top. A box is obviously asking to much but could you possibly spare a few sheets of bakery paper? Of course the phone number is just for show. Krispy Kreme gives you a box, and actually takes some interest in costumer satisfaction. read more

Rainbow Donuts - Donuts Near Me - Diamond Bar, California

I only let myself have donuts maybe once a year, so it was kind of a letdown that when they opened they didn't have hot, fresh donuts. They were a bit old and kinda dry but still edible, just not amazing. The woman was really friendly and nice so I felt bad that I didn't like them more than I did. On the other hand this also means she was a bit more talkative than I can handle before I've had my coffee and cleared the morning cobwebs from my brain, lol. Sadly I would rather buy an amazing donut from a cranky bitch than an average donut from Glinda the Good Witch. read more

Perfect texture between cakey and bready! Love the donuts! Great price and the lady was really sweet too. Remember to bring cash just in case :) read more

Rainbow donuts is very good donut shop and they have drinks like milk coffee water bottles etc :) I will come with good friends soon. Affordable price too :) read more

BEWARE: Shady Shady Shady! I have been visiting this doughnut shop the last few months and have always been helped by the same lady in the afternoon. She gives you doughnut holes while you're waiting and slips 2-3 doughnut holes in your bag after you've made your purchase -- But she doesn't tell you that she's charging you for them!! This was confirmed today as I went with another suspecting friend. I ordered 1 doughnut, but she charged me $1. In the bag, she had placed 2 doughnut holes without telling me. My friend ordered 1 doughnut, but made sure to say, "no doughnut holes please", he was charged $0.85. I recalled a number of past occasions that I had been given doughnut holes without asking and didn't find out until I later opened the bag. They don't give you a receipt. My bad for not asking for one or doing the math until today, but this is SHADY business! I hear the guy in the morning gives the doughnut holes for free... this is not the case with the lady who works here. BAD. With that said, the doughnuts don't taste bad. read more

Great place! Always friendly staff and the donuts are always fresh and delicious! Plus they're only $1! Also recently renovated, looks great and always clean. read more

I will come by here on my way to work when I need a donut fix. The owners are always very friendly and the donuts are very fresh and tasty.

The donuts here are good, the service is a nightmare. The first couple of times I came here I was told I was being 'given' a donut along with the one that I ordered. As it happens, I was being charged for what I didn't order. After realizing this, I'd kindly say 'no thanks' whenever I was 'offered a donut'. But recently, when ordering a dozen, I was charged $11 by the lady who works there in the afternoon, when they've always been $10. I asked the owner (who works the morning shift) how much a dozen are, to which he said $10.50. When I said I'd recently been charged $11he showed no concern whatsoever, and defended his employee's shady practice. Ultimately I realize $0.50/$1 is no big deal, but the principle of fair and honest service is not something the staff at Rainbow Donuts value. read more

Are you awake at 4 or 5 AM? GO. I don't even care if you're not in the mood for donuts, just GO. My friends and I have frequented this place on several early morning occasions after a long night out, and these are seriously THE best donuts in the area. I've tried other Rainbow Donuts locations, but this is by far the best. Their donuts are big and tasty, and they're especially delicious when they're fresh. The owner of the place is SO friendly, as well. Just this past weekend, my friends and I walked in just as the place opened at 4 AM. My boyfriend wanted a chocolate chip bar, but the owner said that it would take a few minutes longer to order, since he was still baking it. We said that wasn't a problem, so we all sat down to relax for a bit. In the meantime, as the owner's constantly filling the display shelves and tending to the donuts baking in the back, he comes out to the front with four cinnamon rolls for us-- for free! Once the other donuts were done, we ordered some more. I ordered a maple cake donut, and the icing was perfectly sweet, and the cake wasn't too dry like it ends up in many other donut places. One of my friends who ordered a dozen donut holes said the owner gave him more than he ordered, again, for free! This guy is amazingly nice! On a previous visit, my boyfriend ordered the chocolate chip bar again (it's seriously yummy and gigantic!), and the owner apologized for the donut being "too fresh," so much so that he couldn't put it in a bag because it would stick to the sides. Too fresh?! I love this guy! I definitely recommend this place! read more

This place is DA BOMBBSKIES! I rarely get excited about donuts, but Rainbow hits every note. The shop? Adorable little mom and pop place. The service? AMAZING! As soon as we walked in, she gave each of us a donut hole and offered us coffee! FOR FREE! The prices? SO cheap! and now for the most important part: THE DONUTS. Seriously, some of the best donuts I've ever had in my life. So fluffy, yet just the right amount of crispy. Not too sweet and full of flavor! All in all, worth every penny. I will always be a loyal customer here! :) read more

Donuts is not bad, but the lady who work there is mean, and tricky. I was buy 2 donuts over there is sure be 0.9$ for each, but she tell me total is $2, when I look at my bag I found out I got 2 extra donut hole in my bag (she not even tell me first), and I buy a coke for $1/can, then I ask for small cup of ice, she tell me will need $0.5 extra. I was like WTF, that is not how you run a business lady!!! So, here is the 2 star, I was think to give one star only.... Huh... Whatever... read more

Finally, i've found it ... the perfectly glazed donut. If you're picky about glazed donuts like me, then you know what i'm talking about. That thin coat of glazed sugar, slightly harden, but when you bite into it...all soft and moist on the inside. Similar sensation as when you eat m&m's. That's how they make'em here..... SOOOOOOO GOOD !! Shop owner let me try their new "Thai iced tea." Oh WOW ..... another hit !! Two thumbs up to the owner!! read more

I've been picking up donuts here for parties for my daughter. All different functions. And I do not honestly with a conscience do not see anything bad about this donut shop. The man that owns that works really hard. And I don't think he deserves the nasty comments and reviews that were left here he's been in business for many years. When your momma said if you ain't got nothing nice to say don't say anything at all. I think you should do it just keep your trap shut this is a nice place they make good donuts and they don't cost a fortune like Krispy Kreme. I don't think it's fair to put negative reviews here. If there are it's with malice and forethought. Thank you rainbow Donuts love you hope you stay with us for a long time. read more

Local doughnut shop in my neighborhood! :) It's been here for ages now and used to stop by to get sweets for my class parties back when I was in high school before going to school. Such nostalgia! I would normally order about 2-3 dozen doughnuts and they always came out to be so cheap $17-$20 and the family working here is always so sweet and generous with bright smiles on their faces. I do recall that the doughnuts aren't as fluffy as KK, but still very delicious especially their blueberry doughnuts was a favorite among the class. :) read more

The ham and cheese croissants are to die for here! I work directly above and there was a point in time where my friend and i got so hooked that we would buy like 5 a day. I calmed down alot since then though haha i limit myself to about 1 a week now. I get coffee and donuts from here almost everytime i have a morning shift. The coffee is a little on the weak side but if the lady worker is there just let her know and she's always more than willing to make a new stronger batch for you. She makes the best coffee imo! Nice and strong just the way i like it! Peanut butter cookie is also super delicious here. It dissolves instantly in your mouth in a good way. Sounds odd but I'm just terrible at descriptions.. just try it out you'll understand what I'm talking about it's amazing~ read more

I love the Thai tea here a very good friend and coworker always brings this to work and I'm always asking for more!

Best donuts in Diamond Bar. Owner always throws in extra donuts and is very nice!!! I highly recommend this donut place :)

Amazing donuts & breakfast sandwiches!! The owner is so sweet. Clean place & great quality ingredients.

DELICIOUS!!!!!!!!!! Must say the breakfast sandwich the donuts the coffee everything was DELICIOUS! I can't wait to visit from Chicago to a California read more

Because I am a local, I had to write a review about this place. It has been here for as long as I can remember and it has been the same owner all of these years! KUDOS to him. Working in a donut shop, you have to be a pretty patient person to deal with all of those indecisive customers who can't make up their minds...like myself. He has always been so polite and welcoming! Not to mention these donuts are delicious and affordable. It's nice to swing by this donut shop on the way to school or work in the morning every now and then and grab some coffee and a donut! read more

Krispy Kreme use to be my favorite. Not anymore. This place has them beat easily. And when I went, the guy was there. He was nice and patient. read more

Lovely register lady comes out to the parking lot to mad dog and yell at you if you park in the fifteen minute parking spot in front of her shop. Even though I'm just dropping off my kid next door and will be gone in two minutes, I enjoy sitting there for ten more minutes to watch her squirm as she sits there "protecting" her spot. The extra star is for the free donut holes that the male owner would top off my box of dozen donuts with. read more

Love the donuts here! I particularly love the chocolate twists here! They have just the right amount of chocolate on them and the dough is to die for! I know when I come in to this shop I can expect freshly made, quality donuts. Also sometimes I get a free donut or a few donut holes. Would highly recommend and if I'm ever craving a donut... or two, I come here! read more

Their glazed donuts are not only delicious but are about 25% bigger than the average glazed that you can find at other donut shops. It's fluffy on the inside and slightly crispy on the outside. We initially came here the first time to get powdered donuts but they don't make them so I opted for a crumb cake donut. It was just ok. Their yeast donuts are definitely their signature ones. Service has been fine on every occasion we've gone which has been between 7:30 - 10:30 am on random days. The same man is always running the store. The shop was smaller than I anticipated. Cash only. read more

See all

Wow, this place has totally changed! Apparently, there's a new owner and the donuts are fresher, the store is sparkling clean, and with an adorable new rainbow paint job! I still can't believe that you can get anything for a dollar, but here I got the most delicious apple fritter I've ever had for a buck, there isn't even tax. I visit Diamond Bar regularly and will definitely be back. read more

DONUTS BY MY HOUSE!!!! I'm a sucker for any place I can walk to. Maybe I'll review the post office after this. Haha... nah. So this place has been around and as a local, I am so glad it's still here what with everything closing shop (ie. framing place next door). Like a decade ago, this used to be THE place my mom would bribe my sister and I with. Be good this week and I'll drive you to Rainbow Donuts! It was the Tuesday spot, man. Yay for donuts! Feels like I'm ordering from inside their home because of the pictures all over everywhere. I think I shall come here tomorrow. read more

The donuts here are great! I love getting donuts holes so I came by before work to get some. The lady gave me a free donut hole to try which was nice. She charged me $3 dollars for 12 donut holes.. Last time I think I paid $2. The prices on donut holes aren't placed on the board so it can't say exactly how much it is (I don't come here too often) but she also handed me a sugar twist donut that I did not ask for..? She kept pushing it on me saying try it and that she warmed it up for me. All in all, the donuts here are great! Not sure exactly what she charged me for though.... read more

Rainbow Donuts - The donut holes! They're delicious.. I ate the other stuff before sitting down to write the review... Oopsie - Donuts Near Me - Diamond Bar, California

I tried this donut shop for the first time today and must say these donuts are excellent. Very fresh! It's hard to find a good old Time donut shop these days. And I am glad to say I will be returning:) read more

On a recent visit to my boyfriend who lives in Diamond Bar I was really wanting doughnuts. I used to work in a doughnut shop and since I moved to Florida about a year ago I have been craving really good doughnuts (Dunkin Doughnuts is a sorry excuse for them) So, he took me to Rainbow Doughnuts and not only was the guy behind the counter SUPER nice, the doughnuts were absolutely amazing!!! It made my first visit to Diamond Bar a little sweeter. No pun intended. :) read more

First time going here, came on a Sunday (around 8am) morning to get a dozen donuts. Saw tons of donuts on display, they all looked so good! Ordered 3 chocolate, 3 glazed, 3 sugar, 3 sprinkled. Paid and left. First thing I felt was that the box was not warm. That's fine, I can eat donuts room temp, would of been better if they were warm though. Second, got home and took a bite into a glazed one. it was not soft/fluffy. It was just two inches thick of dough. The man and son(?) that work there are very nice and patient though. read more
