Walked in to try this place for the first time today and it will be the last I guess. The Filipino woman at the front counter has the most horrible attitude and seems as though she hated her job and did not want to be there. Very rude, dry, and not customer friendly whatsoever. Won't be coming back. Donuts were not fresh anyways. read more

Coffee is crappy prices are insane for stale donuts . Both of these things we're sitting around for at least 24 hours at least.

Been buying donuts here for years for my company. Give them about 70-100 a month in sales and new guy at the counter questions my purchase. Never an issue before. Tells me they card everyone with a 20$ purchase and guy needs to me is buying over 20. It's a shame. read more

The fact that this pace is 24/7 truly makes it for me. The donuts are good, and the service is always nice. They don't stop making donuts so you can get goods ones late at night. read more

I've been coming to this shop for over 20 years. My mom used to wake me up at 1am and we'd go get a dozen doughnuts while they were still warm. I love that they're 24 hours, and they are close enough to my place to satisfy my late night cravings. Plus they have doughnut holes which are awesome. My only gripe and reason for holding back a star is that their dozen is $3 more than the other Mr. Blues in Corona (not affiliated apparently) for the same quality doughnuts. read more

This place is great! The donuts are beautiful, clean, and delicious! Mr. Blue is very welcoming! He smiles and welcomes every customer and even tries to converse here and there. He remembers his customers. He constantly keeps busy, making sure his shop always looks presentable. The shop is in a little plaza next to a high school, so don't be turned off by a group of teens in/outside his shop! He handled them all very well and works quickly. They also have donuts I had never seen before! This is always exciting for a donut fan like me, haha. read more

See all

By far the best donuts I've ever had. The glaze is amazing. The chocolate donuts and the chocolate glaze does not compare to any other donut stores it's way above. And they're always hot and fresh daily. I tell everybody I don't eat donuts out of the pink box, because from Mr. blue's they come in a white box read more

Meh. Not the worst donuts I've had but not the best either. A little on the greasy side and not very tender.

Mister Blue's Donut Shop in 5 words, Donuts You Can Die For! First of all, Mister Blue's Donuts are famous not just in Riverside, probably around the world. Krispy Kreme, Yum Yum donuts, Dunkin donuts have nothing on Mr. Blue's Donuts. I feel those shops make the donuts with inexpensive material. Delicious, delightful, enjoyable, flavorful, fluffy, mouth-watering, tasty are some words you can use to describe the donuts Mr. Blues make. read more

So my kids and i were craving donuts, so we went to this place for the first time and is our last time too very bad customer service the lady seemed like in a very bad mood. Definitely not recommending this place. Also the donuts are not fresh. read more

I am confused. How is this a 24 hour donut shop but we went in at 9pm and there were no donuts out. We asked when the next batch would be coming out and we're told they wouldn't. Also the man did not even acknowledge us when we walked in so we stood there like hello earth to dude. Whatever happened to customer service. read more

You know we grow to trust Yelp reviews. You are willing to go out your way for a restaurant with a great review. Sometimes it DOES NOT WORK IN YOUR FAVOR. We have donut days when we reach goal. I am a huge fan of Baker's Donuts but they are constantly running out of certain donuts and today the customer service was bad. I left--I do not pay for bad service. I checked Yelp for the donut shop with the next best reviews. I drove completely out of my way. Hands down these are the worse donuts we've had. At this writing I see half eaten donuts on desk as well as those that have not been trashed. I feel hoodwinked on these donuts. I honestly wish I can call my bank and say my card was stolen and they bought donuts! Get my money back. Lol. Some of you will still believe the review hype and go anyway. Buy a donut hole or ONE donut And try it for yourself first. My donut hole tasted like a lightly glazed hush puppy. read more

My search for the elusive ham, egg & cheese croissant took me to Riverside this past Friday. I pulled up expecting disappointment--I've been skunked so many times already. I take a look at the menu and don't see it. I ask the cashier if they offer it. He said that he can make it for me. I say, "do it, do it." Hot croissant, egg, ham & cheese. YESSIR! But it's cash only folks, so I had to run over to the Albertson's around the corner and got stuck with $2.50 worth of atm fees....weak. The croissant wasn't THAT good... read more

Oh man. I was out in Riverside this last week and drove by this place that serves up some good and bad memories for me. I use to get super high with an ex and then drive over here. If you get there right after midnight they always had fresh doughnuts. And you can't beat a fresh doughnut, especially when the frosting on the top is still dripping down the sides. Oh man I miss this place more than my ex. read more

Your pushing your younger generation customers out of your donut place thanks to allowing your older ladies to sit in there for long periods of time and try and tell other parents children what to do, I can discipline my own children just fine, she was a rude old lady in the way that she spoke to my child to remove his feet from a chair, she was targeting him because of his sexuality too, so I will not be visiting this place again! I can't stand it when others step over my responsibility as a parent to discipline my own children, I also hadn't had a even one minute to tell him to take his foot off the chair. I have been very ill, not contagious at all, and came to enjoy a donut even without having much of a voice to use, and enjoy my donut. But it didn't happen we were harassed in my opinion. read more

This place is always our go to when me and my family are craving donuts! My favorite is the blueberry glaze or the strawberry cream cheese croissant. The blonde lady was very nice and even suggest if my husband wanted his cinnamon roll warmed up! He cant have it without doing so now! read more

This is THE donut shop my parents took me to when I was growing up. It will always have a special place in my heart :) Honestly, I think they have the best donuts in town. I've tried other places and they're usually stale, dry, or just not as good. Mr. Blues is also open 24 hours, so that's a plus. I only had one bad experience there... after my brother's wedding (2005), I went here and no one came from the back to help me. One guy saw me and just went back to doing what he was doing. After 3 minutes, I left. Haven't had that problem at any other time. read more

These are hands down the best donuts in Riverside! And the customer service is exceptional! I am always greeted with a smile and a warm hello. Their donuts are always fresh! Amazing! I have been coming here for 20+ years and have never been disappointed. I was shocked to see it only had 3 1/2 stars. Definitely 5 stars. Thank you for being consistent and always having amazing customer service. read more

It's so-so. Gets it stars for being next to the drive-in and next to Sushi Asahi. Get sushi, get donut, see a double header at the Drive-in. Done. Tried the apple fritter and felt like I was just eating a fritter, minus the apple. Boooo! It'll do I guess... Cash only. read more

Even during these crazy times, this donut shop serviced me extremely well. I ordered over 100 donuts for my wedding just one day before the big day. They accommodated my request and even gave free extra donuts. Owner and staff was very sweet and even helped to load my car with the donuts. Donuts were perfect quality... definitely exceeded my expectations. read more

My family has been coming here since my mom was in high school. I grew up eating these donuts before school, and now I bring my own kids here. They've always been the nicest people and the donuts are amazing. read more

These donuts are my late night craving! Get a blueberry glazed and a chocolate with coconut for sure, and when you get home stick them in the microwave!! I'm not a fan of their ham and cheese croissant, or their apple fritters, but their regular donuts are cheap and delicious. Bring some cash! read more

This is definitely my go to place when I feel like snacking on something at night. Their donuts are to die for when freshly baked but like any other food product the long it sit out for the more it loses its texture and flavor, so if you ever decide to give this a try I recommend waiting for a fresh batch of donuts or some that are somewhat just came out. read more

I love this place. They don't do all the crazy new stuff that is popular right now, but their donuts are great! It's a true old fashioned donut shop with great service and great atmosphere. I love bringing my kids here to sit and have a donut (and hopefully we'll be allowed to do that again soon post-COVID). read more

I love this place, we been coming to the little shope since i was a kid, I always order a chocolate milk and a maple bar, the donuts are always fresh, and delishes. I recommend the Apple fritter. read more

I love these donuts they are soo good. I use to always come here when i was small . If you are lucky enough to get there when they are fresh they are amazing read more

Quick and easy. The donuts are good and people are nice enough. I like the coffee, the croissants and decent, but the bagels taste like they are store bought. read more

Staff was extremely friendly and helpful. I purchased a bakers dozen for $9.75 and she even threw in a free donut. Donuts are fresh and moist. I will definitely be coming back to this donut shop. read more

I had an apple filled bear clawish looking donut and it was soooo moist like they just prepared it. I appreciate fresh donuts mid-day vs. stale donuts mid-day. read more

I was craving donuts about an hour(9:30pm) ago so I stopped to a few up. This place is open 24 hours so I expected to find at least a decent selection but they were pretty much empty. Disappointing. What's the point of opening 24 hours when the donut trays are empty. The donuts left over didn't look appetizing so I got one of their apple fritter. It was okay. Still, wasn't satisfied with my experience. read more

Rude rude! Our first time here. We walked in all trays were empty. The lady behind the counter just looked at us and said "Thats all no donuts thats all I have" not even 1 glazed. We just turned around and left. read more

Pretty solid lottery shop that also sells donuts. The lotto machine really stands out here. Honestly the donuts are pretty decent. Nothing fancy like cro-nuts but solid fritters, old fashion, glazed, etc. my parents for whatever reason think this is the most amazing donut shop in the history of the world, but they are from a small town in Oklahoma so their bar is pretty low. The people who work here aren't the friendliest folk in the world but they will sell you donuts. I'll average my three stars with my parents five stars and go with four. read more

The doughnuts here have always been absolutely amazing. We've been getting doughnuts here since 1991. I moved to Oklahoma in 2001 and every time I return to Cali I always get my favorite doughnuts here. The Apple Fritters are the best I've had and tops anywhere else. read more

The worst donuts ever! They always have old donuts from the morning sitting till night. They don't make fresh ones till about 2 in the morning which is what the guy said. read more

The donuts are decent and I probably would have left five stars if their donut cases weren't full of little flying bugs. I can't imagine what their kitchen looks like if they allow the case where prepared foods go and the public to see to actually have bugs in them. Deplorable. Y'all should be ashamed of yourselves. I can't believe this place hasn't been shut down yet. read more

Unbelievably rude! Angry, grumpy guy behind the counter who clearly didn't want to have to help anyone. I ended up saying "That's ok, I'll go somewhere that wants my business." I had initially stopped to get 5 dozen donuts, the jerk behind the counter simply grunted responses as I ordered and asked questions. It looked like the place was a haven for transients and the floors were filthy. I wouldn't even enter this place again to steal a napkin. read more

If I could give this place 0 stars I would, I bought the bakers dozen, and when I got home There was a Hair (PUBIC) in between the donut, took them back to the place, the man there didn't even apologize, and I asked for my money back. Never coming back, How could they have a Grade A. I also emailed the Health Department. read more

I was never a donut fan until I tried mr.blues ... I'm addicted lol I love how fresh every donut is. They are very fluffy and the guy that works there is very sweet. The reason I give it 4 stars is because they only accept cash and I rarely have cash. But that might be a good thing or I'll become obese lol but to be honest they will prob get even more business if they started accepting visa. read more

I used to go to Mr blues all the time, but I work closer to a winchell's now, so when I heard it was national donut day, I got excited to bring home donuts to the family. I was already at Albertsons and decided to go inside Mr blues. NO DONUTS UNTIL 10PM, their handwritten sign said. All the trays were emptied and no one in sight. Finally the older lady came out and wouldn't make eye contact with me, she just said sorry. I'm pretty sure it doesn't take more than 5 hours to make donuts. read more

I came here when I was craving donuts one evening I hadn't had one it a while I got a maple bar and a apple fritter for myself and others for my family at home. They where your average donuts nothing to special hits the spot. Was fairly busy being later in the evning. Place surrounding it didn't feel to good got a sketchy vibe form the people lingering in the parking lot of this place. But otherwise good donuts read more
