Best. Donuts. Ever! The lady behind the counter was very friendly and they had a really wide assortment of donuts despite being kinda late in the morning. Immediately, just from initial appearance, you could tell these donuts were better than average. When we got them home, the fam and I tore into the dozen. Everything was so good! You can really taste the difference. Even though Winchell's is just down the street from my house, looks like I'll be making the drive out to D-Bar when I start jonesing for these sweet treats. read more

Came all the way here for breakfast sandwiches at 430am. When we got there the guy said no sandwiches until after 6!! Wish we would've known that or would not have made the stop a mile and half off the freeway. read more

We found this little donut hiding under a big shopping center, not knowing it was there every time we drove by. Our usual donut place was closed so we came here and it was good. The donut sizes were descent. The only thing we didn't see was donut holes. Not sure if they ran out or they just don't have them. read more

Ordered the egg, cheese, and sausage croissant and it was seriously so GOOD!! Definitely my new go to spot for a delicious breakfast sandwich!! read more

Stopped on by in the afternoon one day on my way to somewhere. Have noticed this donut shop for awhile but never really went in until recently. Went in and got myself a fancy donut. I got the oreo donut one which was pretty good. I should have came early in the morning for the fresh ones. Next time, perhaps for the same one. read more

13 words. The Apple Fritter was absolutely the best thing I've ever eaten that day. As a first-timer (to the store, not to doughnuts), I chatted up the woman behind the counter and pleaded for some recommendations. First, she was extremely nice, and even gave me a free donut hole to quench my hunger while choosing from the buffet. Like I mentioned earlier, the apple fritter (or whatever it's called - it has apple in it, and tastes 'frittery') was simple divine. I went in around 5PM on a Friday, so I was a tad nervous that the treats wouldn't be fresh, but I was pleasantly surprised with every bite. There were a TON of donuts available to choose from, so I'm guessing they usually get a late crowd as well? TL;DR: Great donuts - personally recommend the 'apple fritter'. Ask for a free sample because who doesn't appreciate the free things in life. read more

Stopped by here cuz I was craving a smoothie. I was next door at Gracie Barra Jiu Jitsu and one of the instructors Daniel told me how good the Rainbow Donuts made smoothies. So I went and gave it a try. I met a girl named Pin. I'm hoping I spelled her name right. But she was the sweetest thing ever! Super nice! I asked a couple questions about the smoothies and she helped me out right away. The smoothies are made by real fruit. They also have the option to put boba in the smoothies which was awesome cuz I love boba! Pin was super nice. && the smoothie I got which was Mango, was really really good. I loved it! Definitely will be coming back whenever I'm at Gracie Barra here in Diamond Bar. Come check out this place you guys if you want some good donuts and great smoothies. P.S. thanks so much Pin for all your help and kindness! read more

This review is based solely on their blueberry donuts. I'm not sure if this is the same Rainbow Donuts as the ones I've been to in Cerritos and Anaheim but the blueberry donuts here didn't look or taste anything like the ones I've tried. Usually I can spot a blueberry donut by their color (darker than regular glazed with blueberry spots) but I couldn't pick this one out; I had to ask the employee for it. When she gave me the donut I couldn't believe it was a blueberry donut. I could barely see any blueberries and the shape was totally different. When I took my first bite, I was disappointed. I really couldn't taste the blueberries because there was hardly any in it. I hate to knock the review down on a place that has so many rave reviews but blueberry donuts are the latest craze now in the donut world. If this place doesn't keep up with the rest of them, it might be hard to compete. Maybe they have other flavors that are pretty legit but nothing else looked that interesting to me. read more

Rainbow Donuts renovated their shop and further enhanced their sanitizing practices during this COVID-19 crisis. The new and honest employees are so kind and have been giving a few complimentary donuts when I've ordered the selective dozen (about $10.50 per dozen). Glazed twists, the maple bars, frosted & sprinkled round cake donuts, and old fashioned blueberry donuts are all favorites!! There's also limited indoor seating if you'd like to sit in to eat. read more

I walked in and made my donut choices based on the menu which was plainly visible with donuts types and prices. Buttermilk bars were plainly prices at $1.75 each. When I got to the cash register I was charged $4 for 2 buttermilk donuts. When I questioned the total price should be $3.50 per the menu, the girl, sorry, prices went up... I just said ok, I wont be coming back. The buttermilk bars were the absolute smallest donuts I ever paid $2 each for. My church, Landmark Church of Diamond Bar, buys about 7 dozen donuts each Sunday. They will be learning about my bad experience. Donut shops are plentiful in the area, one shop is about 2 blocks from the church. The church needs to move on to a new donut shop. Additionally, they charge 75 cents extra for credit card purchases, and 2 extra for credit card orders over $35. Some people have brains and no money, some people have money and no brains, this shop needs to shop for better credit charge services, like Square Up. They also need to be robbed of a large sum of cash, so they can realize the safety and benefits of cordially accepting credit cards. read more

The lady who works here either doesn't know how to calculate or tries to rip you off. I ordered two dozen and she said it's 24 dollars. I vividly remember this because I originally wanted to buy twenty but she insisted buying two dozen is better because it is only 24 dollars. On the menu, it said a dozen is 14 dollars so I thought if you buy two dozens you get discount. She charged me 28 dollars and I told her she said 24, she said it doesn't matter what she says with her mouth because the price is written on the menu. I would completely understand if she made a mistake and said sorry but it seems like she is doing this to rip off customers. NEVER going back here again. read more

Delicious, flavorful donuts and this small shop in diamond bar. They had blueberry which is my definite favorite. Their breakfast sandwhich was also quite good. Highly recommend the bacon egg croissant sandwhich. Friendly quick service and ample parking in the lot shared with Albertsons. read more

I randomly came here for donuts one day and I got a Thai milk tea with them. Now I find myself waking up thinking about the Thai milk tea and donuts- hahahahah! Their donuts are always fresh and the staff is really nice. read more

I live in Diamond Bar. Just went to rainbow donuts for the first time and last. 4 regular donuts cost $8 something. WTF? And the donuts weren't that fresh. There is a donut shop off the 57 and Diamond bar blvd where the donuts are always fresh, nice workers and the donuts are around .80 cents. Thanks read more

Great customer service and high quality donuts. Their Cinnamon rolls are GOALS! Lady working was very friendly and helpful. Will be returning again read more

Went to this donut shop around the corner from my hotel that I'm staying out. In from out of town (from the bay area) and omg these donuts are so rich in flavor and the bread is so soft. So delicious, literally the best donuts I've ever tried. The lady that was there was so sweet too, she was so sweet to my twins. If we are ever in town again we will definitely stop by. Thank you! read more

The donuts are okay but I don't like the lady's behavior. this morning, after took out my credit card to pay the donuts ( Here charge extra 0.75 for use credit card), and she just moved to a new customer for the new order but didn't ask me to want the receipt or not. Then I asked her " no receipt for me?", and she leaked an unhappy expression and asked me "you want a receipt?" I said "yes". I've been living this city more than 7years, and it was my first experience like this morning and who knows I need receipt or not!! #NOT FRIENDLY #BAD SERVICE #EXTRA CHARGE for CREDIT CARD USER read more

Great new owners that really know how to make donuts. The apple fritters are amazing and the blueberry are a close second. They have the essence of donuts down. Super crispy exterior with the sugar crunch of Creme brûlée and a soft interior with the bust of fresh tasting donut goodness. They are really the only sweet that I would break my diet for. My whole family are fans of these donuts. Even used it as a birthday cake. Haha but a huge hit. read more

A few months ago, new owners took over and it has been such a positive experience! The menu board is absolutely gorgeous and perfectly handwritten, the mural on the wall brightens up the room and the donuts, oh the donuts. They are spectacular. Every time I stop by, they look absolutely professional, freshly made and absolutely delicious. The owners are such sweet and kind people who really care for their customers and their city. I hope that whoever comes across this review will go and check them out. They also have really delicious breakfast sandwiches as well as smoothies with boba! read more

So good! I got the raspberry jelly and loved it. The donut was very soft and filled well! read more

Rainbow Donuts - Raspberry jelly, chocolate twist, glazed twist - Donuts Near Me - Diamond Bar, California

Simple donut shop...but the simple chocolate glazed and caked donuts are irresistible. Not greasy...so fresh and warm and light and fluffy...the donuts taste as if they were made with love and care. It's the best way to describe it. read more

I've been going to this donut shop ever since I was a kid. About 25 years or so. Every Saturday morning we'd go get donuts from here. The owners have always been so kind and their product is top notch. My top 3 go to choices are the white frosting with sprinkles, the Apple fritter, and the glazed twist. The coffee is pretty good too. You must give this place a try if you haven't already read more

I have fond memories of this place. We were DBHS class of 2007. Back then I had Mrs. Lemon for first period. Always up at the crack of dawn but one thing that always brightened my week was Fridays. Simply because Mrs. Lemon always brought two giant boxes of donuts for her TAs every single Friday. I was her first TA of the day and always had first dibs and they were always still warm! I've tried just about every single donut they offer because of Mrs. Lemon! Even after HS I would frequent Rainbow Donuts because that's what I was most familiar with. Now almost 15 years later, I am no longer living in DB. I have gone to many donut shops far and wide including so many of these trendy/fancy donut shops that's been popping up just to realize that I didn't know how good I had it back then. I find myself comparing most other shops to Rainbow Donuts. Clearly I consider their donuts to be the standard of what excellent traditional donuts should be. My favorites are the: Bavarian Cream, Traditional Blueberry, Apple Fritter and the giant Cinnamon Roll. read more

Kind of upset I didn't discover this place sooner because this place is amazing. They sell different kinds of donuts but my all time favorite is their small donuts. These little donuts are so good when warm. Every time I bring a box to my family or coworkers they always ask me where I get them. Such a crowd favorite! Definitely will be back for the other flavors! read more

Such a gem of a find in diamond bar. I was on my way to the office when I thought I'd be nice and bring my co-workers some sugary fried carbs. The man in the store was the absolute nicest, most generous man ever. He accommodated my indecisiveness without batting an eye and even gave me some donut holes on the side. My go-to is usually the custard filled chocolate, which wasn't so great here but otherwise, no other complaints. read more

I've been craving donuts for a bit and decided to finally stop by since it's so close to home. I walked in and got the usual kind of donuts I love which is a raspberry filled glazed donut. Which was super good! I had read reviews on their blueberry donuts and remembered at the last minute too! That one is my favorite so far!!! It was soft and had the perfect amount of blueberry taste where it wasn't overpowering (it has actual blueberries in it). The lady behind the counter was the sweetest! She gave me a donut hole to taste before selecting my options - which was actually soft! She was really sweet and actually has a conversation with you! I'll definitely be back anytime I have a donut craving!!! Especially for the blueberry donut read more

Don't trust the Yelp map! Its wrong! It made me drive around in circles! GRAAAAAAAH SO AGGRAVATING. Rainbow Donuts is actually on the same side of the street as the post office, in the same plaza as Albertsons actually. 80 cents for a legit Old Fashioned. They got chocolate glazed, regular glaze, and blueberry Old Fashioned. I LOVE OLD FASHIONEDS! COULD NOT RESIST THE PRICES. Ended up with one of each kind for a total of 3 donuts. They are all decently big, no shrimp sized donuts here. LEGIT I SAY. LEGIT. Best donuts in Diamond Bar? read more

Rainbow Donuts - Front entrance. - Donuts Near Me - Diamond Bar, California

The best donut shop I go to for the mornings I'm craving a sugar donut. Other donut places in Diamond Bar have too much sugar, or the sugar falls off because the donut is too hard. Rainbow donut has the softest donuts and a great selection, not to mention the donut holes. I love donut holes! I used to go every two weeks in the morning to start the day with a dozen donut holes. The guys that works there is so nice and remembers everyone that walks in. He would say it was nice to see me again, and asks if I wanted a dozen donut holes without thought. I hope Rainbow donuts will stay forever. Price is cheap too! read more

Right down the street from where I live, I remember this place from when I was a wee lil' kiddo just wanting my fill of the sweet stuff. This place definitely delivers. It's a small store with nothing more than a counter full of donuts.. but those donuts are always fresh and soft... my favorites being the glazed jelly ones! Really cheap too. read more

Absolutey love this place. My family and I get donuts here every couple of weeks. The lady is always nice and friendly. 10/10 recommend.

This is my TO GO to donut store in the Diamond Bar area. They always give a couple of extras and the owners are super nice. The donut holes are amazing and not too sweet and very nicely glazed. I definitely would come here over other chain donut stores and the price/donut is so affordable. Highly recommend and always a joyful post work out reward. read more

Great little breakfast and donut place . Donuts are always great . Had a BLT this morning before my donut. Most excellent start to my day. The staff were the friendliest people. Thank you read more

I've gone to this donut shop about three times since I moved here and every time I've gone there the lady that works there, not sure if she's the owner, is always rude and curt. The donuts are typical but the customer service there just ruins the experience. I'll take business elsewhere. read more

So many memories here, I love the donuts from here. Even though I grew up on donuts from both Donut Tree and Rainbow Donuts, Rainbow Donuts knocks Donut Tree way out of the ballpark. Service is always great here. Prices are very, very reasonable. Donuts always, always taste great! Never dry or lacking in flavor. Sometimes when you go, one of the ladies sometimes gives you free donut holes as well! Maple bars, old fashioned glazed, glazed buttermilk, apple fritters, and etc! read more

All their donuts are good; but their business practice might be a little tricky. I felt like both times I've been they start throwing in more donuts for you "for free" then actually account for it in the price. I just stick with some old fashioned blueberries. Donut Holes are pretty good too. read more

Chocolate cake donut is moist and tasty. The one with chocolate sprinkles is even better.

Sorry--The one staffer on duty at Rainbow Donuts was a bit surly and pretty unfriendly during our visit. Not a welcoming atmosphere in any way. The employee seemed like one of those disinterested people only working there for a paycheck. I greeted her with a friendly "hello"--no answer--I asked her what donut was fresh, and she simply shrugged. The donut I did buy was dried out, without much chocolate flavor. 100% #Pass. read more

Do not bother with this establishment. Hours listed on yelp and on their frontdoors are inaccurate. Arrived at 5:30 PM on multiple occasions and the place is closed. Seems like the owners or whoever is working here leaves whenever they want. read more
