Apple fritter and a free donut hole!
Steve F.

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.

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.

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.

a variety of donuts in a box

We got these for our early morning meeting today. I usually try to stay away from donuts. The blueberry old fashioned was so delicious and fresh! They have a nice variety. Friendly and good selection.

Blueberry glazed old fashioned donut ($1.75), sprinkled donut ($1.5), and half dozen donut holes ($1.75)

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.

My husband loves going here since he was a kid. We asked if they could make it for our donut wall, and it came out so great! Thank you so much!!! We love Rainbow donuts

Looks soo tasty  someone pickup one already ^^ Ham, egg and cheese on croissant sandwiches
Sunnie K.

Wow Rainbow Donuts did an awesome job making delicious breakfast sandwiches. 20 croissant ham egg and cheese breakfast sandwiches which feed 40 peoples because it was cut in half. I had to pick up before 7 am and it was ready. They put the sandwiches in aluminum tray with aluminum foil to keep it warm. Very thoughtful. The owner, manager & staff were very friendly and professional. Everyone loved it !!! Visually and tasty !!! I heard lots of happiness thanks

Two boxes of the fluffiest donuts in town.
Eva B.

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.

Just cruising through town and wanted some coffee and donuts at 4am and came across this place. Variety of Donuts are too cute & good & soft! Even had Vietnamese coffee so great! And the man who helped me was very nice and had a good attitude. Also can't forget it was really clean in there too. Yes I would come here again.

Nice selection of tasty donuts!

Are the donuts kosher? Do they contain any gelatin?

Best to call the area we're you are planning to buy your donuts. Asked the chef or manager. And if same pastries who deliver they're donuts supplies other cafe inside Aqua. So you will be aware. Cause now Aqua have 3 locations

My partner has been on a sweet potato kick. From a guy who opts out of potatoes except for fries,…read morehe suddenly discovered the flavors of sweet potato. I thought, what about a sweet potato cake. Found two Korean bakers that had sweet potato cakes on the menu. It was kismet this bakery was just down the street from a restaurant we chose for his birthday dinner. I called and the owners took down my name and the fact I'll be there around 7 at night. Didn't even take down payment info or number. I got there a little after 7 & saw they had sweet potato cakes left. Reasonably priced too! $40 for larger and $30 for smaller. I thought $30 would work for just 4 of us but for $10 extra, my partner thought we should splurge. The owner remembered me from the phone call and addressed me by name. While his wife was ringing me up, her husband came up to me with a bag of bread to throw in. That was so sweet. With their service, variety and price point, we'll be back. The cake was delicious too. Not sure how cold their display is but the cream filling in the middle was just cold enough to taste like soft serve ice cream. Intentional or not, it was delicious!

Ordered a last minute chocolate cake for my brother's birthday yesterday. The bakery was so sweet,…read morethey even included 2 extra pastries as a thank you for supporting their small business. The cake was packaged very carefully and the chocolate was so good. Perfect amount of sweetness and the cream was light and delicious. Will definitely order from them again.

It appears that they are still in their transition phase as there are still signs of "the Mugs" throughout, including the same menu and company info poster. I got the Banana Caramel latte and it is so good! Slight sweet banana flavor but doesn't overpower the espresso so it still tastes like a coffee drink. Plenty of seating for working and just hanging out. Parking is plentiful, staff is nice, just wish the noise of the refrigerator case wasn't so loud so I could enjoy the background music.

I went on a weekday before noon and had no issues with finding a spot. For ordering, they had a kiosk inside with pictures for reference as well. It does accept American Express. After ordering, it only took a few minutes before it was ready. As for the atmosphere, there were a few other people, but they were mindful of noise. The music was also moderate, so I was able to focus without any earphones. There was plenty of seating from the center table to seating at the wall and even window seats. There were outlets available near seatings at the wall. There was also free WiFi as well. At first it indicated you would only have WiFi access for 1 hour. However, after the hour, I reconnected and it refreshed the timer. For my coffee, I decided to get an iced Dalgona latte. They provided many pieces of Dalgona. I did ask to get this at regular sweetness and ice. Overall, after the Dalgona dissolved with the ice, it felt like a good amount of sweetness. It was decent, but I've come back to try other drinks!

It's different from your typical bagel shop, with a subtle Korean twist that makes everything feel unique. Even their plain bagel is incredible, with the perfect crisp on top. I always order the lox, and their cream cheese is hands down some of the best I've had. For sweet options, the blueberry wine and cinnamon walnut bagels are so good. The owners are incredibly kind and welcoming. Sometimes they even give out free pastries if you come at the right time, and they are always happy to help. Their coffee is also really solid, especially the brown sugar coffee. I seriously cannot recommend this place enough. It has easily become my go to local bagel spot.

They now have an order on screen menu/ option but still can order the old school way too I always get the avocado bagel it's my go to fave thing! I will say I liked it more when they paired it with a side salad they had this yummy vinaigrette sauce along with it, now they just give a scoop of potato salad which wouldn't be my first choice lol so I usually leave that behind. I have tried the pastrami which is also good! Go early cause they don't have a lot of bagel options or baked goods after 11am! Italian sodas a must! Especially since I'm not a coffee drinker! Will be back soon

There were only a handful of tables, and almost all of them were occupied when we arrived. Everything we tried was amazing. The hot dog roll was crispy, savory, and super satisfying. The ham and cheese pastry was also incredibly crispy with that buttery flaky texture. My favorite pastry was probably the strawberry lemon creme croissant: fruity, bright, and packed with flavor without being overly sweet, which I really appreciated. For drinks, the Korean plum gochu lemonade was unexpectedly addictive. It was refreshing and citrusy with subtle hints of spice that made every sip interesting. Overall, a great spot to grab pastries and drinks while taking a break from shopping. Definitely coming back to try more items.

My first bite was very dry and I wasn't sure what I was tasting. It didn't taste like crab for sure, so I had a second bite. It was bad. I asked one of the workers if I could switch it out with anything, she said she'll ask the manager. The assistant manager came and told me that she cannot swap it out and that I should have read in the description that it's only imitation crab meat. Ok, I can own that, I could have read the fine print. But it wasn't just the taste, it was also the texture, the over fried dried dough... I really wish that she could have been more understanding and more accommodating. It's only a bakery item and not a prime rib dinner. Not only the crab croquette left a bad taste, the lack of service and courtesy also left a bad taste.
