Rainbow Donuts Diamond Bar Reviews
Absolutely LOVE this donut shop. Everything is fresh and you can tell they actually care about quality. Special shoutout to the rectangular chocolate donut with chocolate chips inside — unreal. Soft, rich, not overly sweet, and honestly one of the best chocolate donuts I’ve had. The shop itself is super clean, the staff is friendly and welcoming, and you can tell the donuts are made fresh. Great vibes, great service, and even better donuts. Will 100% be coming back and recommending this place to everyone.
Went to pick up some donuts as a group treat, this place is fantastic! Well stocked with everything from old-fashioned donuts to cronuts - literally something for every sweet tooth. The staff are lovely - very attentive and friendly. Don't miss out on this hidden treasure!
For the past 20 years, we’ve been buying donuts by the dozen for friends and family. Recently, we were surprised to find out that the previous owner Tom had sold the shop; he was much beloved in the community. The new owners are a husband-wife team with years of experience in the donuts/pastries industry. They seem to be wonderful folks working on overdrive to create these delicious gourmet-style donuts. Their donuts are on par with high-end pastries.
Great local Doughnuts. I always get at least a dozen every couple of weeks. The whole family enjoys. The store owners are super friendly. Every time that I go here the doughnuts are fresh and a plentiful. I like the convince of its location. I have only purchased doughnuts so far, but they offer items on the menu that I must try.
Perfect donuts. I stop by every time I'm in town for a dozen. Great variety, usually not too crowded, fast and pleasant staff. Love it here.
This is the nice place I have ever been. The donuts so delicious, the service really nice and the place is so clean. Recommended!!!!

This is one great donut shop not only are there friendly people behind the counter but they make some of the most incredible sandwiches probably 20 different ones I've tried 3 or 4 love each one I've had so go ahead and grab yourself a breakfast sandwich lunch sandwich for their traditional Donuts croissants love this place can't say enough about it Norwalk Raider out
i've been visiting this donut shop since i was very little. it's always had plenty of different donut options available along with the classics. i've always seen people going in and out every morning as i would drive by and i get a craving now and again. next time i decide to take a dozen to my work or home i'll be sure to stop by here.
The lady is very sweet and kind! Great service and yummy donuts!!
Although I am not a huge donut eater, this is my spot whenever I grab some. Everyone here is so friendly and the donuts fresh/crisp. Try the cronut! They have a few tables indoors where I will sometimes enjoy a coffee and chat. Great neighborhood spot
Our entire office is obsessed with this place. We’ve gotten dozens of donuts and donut holes (my favorite), and our collective favorite is their #8 breakfast sandwich (bacon egg cheese on croissant). Their prices are great, service is so sweet, and most of all their stuff is DELICIOUS. Don’t pass on this place for a great treat or breakfast sandwich!
I got a blueberry old-fashioned donut and passionfruit lemonade, and it was delicious! There's also a nice table to chill at inside the restaurant :)
Great local donut shop where you can get all your favorite donuts. Personal favorites are plain old fashion and cronuts. Service is also so friendly. As in many places, fees when using your card. But I always keep cash when I go running and come after for a treat :D
Rainbow donuts, very good coffee. Fresh may be fresh for whoever wants it. Donuts are freshly made every day. Good jobs, rainbow donuts. Keep up the work. Customers keep coming in the best
Best ham and cheese croissant ever! it had a perfect ratio of ham and cheese inside. It warm fresh as well as the donuts.
Fantastic local donut shop. I've been in several times and the quality is outstanding. The croissants are the best I've had, and the breakfast sandwiches are amazing! Donuts are great, prices are very fair, the ladies working are always friendly. I recommend this tiny donut shop 100%
Amazing, fluffy, and perfectly sweet donuts around the local area!! The owner and employees are all so nice, and greet you with a smile the minute you walk in!! Everything is fresh and I have never had a bad experience coming here! Especially for that courteous service 😆😆🍩🍩
Best eggless donuts. I am strict Vegetarian that don't eat eggs and his inventory donuts don't have eggs in the batter. He doesn't even carry eggs in his refrigerator. He even showed me. I been going to his shop since the early 90s. I don't live in DB anymore but I try to make it habit to go once every 2 weeks. Thank you for being in Business.

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
The last 2 time Iwas there I got sick I felt good before it was dirty

I am not sure what happened to the wonderful man that owned this place. The donuts were the best on the planet and he was the kindest and most hard working man. It is under new management. The donuts are not even close in quality anymore. I have been going there for over 30 years... but never again!!!
Do not respect the close time. I came at 1pm on Sunday and they are closed.
