Yum Yum Donuts in San Marcos is one of those classic spots you pull up to expecting a quick, glorious bagel moment... and mostly, they deliver. These guys are famous for their turkey bacon avocado situation for a reason--it's legit. Fresh ingredients, generous portions, and that perfect "California fuel" vibe that makes you feel like you've got your life together, even if you just rolled in half asleep. But here's where it gets funny. I order a bagel already pushing about $12--which, fine, inflation, San Marcos, avocados apparently guarded by federal agents now. Then the guy casually tries to tack on another $5 for a little bacon on top. Five dollars. For bacon. Not a farm. Not a pig. Just bacon. At that point I'm thinking this bacon better come with its own birth certificate and LinkedIn profile. And the best part? Nobody even asked what kind of bagel I wanted. No "sesame, everything, plain?" Nothing. Just mystery bagel roulette. Customer service isn't terrible, but it's definitely operating in autopilot mode. A little more attention would go a long way. That said, the food itself is solid. Yum Yum has the reputation for a reason, and when they're on point, they're on point. Fix the small service quirks and the surprise bacon tax, and this place is easily 5 stars. For now, strong 4 stars--great food, just don't let the bacon negotiate against you. To be honest it all depending on location ex burbank and playa wayyy tastier! read more

The lady at the counter was not paying attention to my order. I wanted tuna they didn't have tuna so I went for the black forest ham. I wanted the meal with chips and drinks. All I got was a freaking bagel. This is the first time I had very bad service. read more

The donuts didn't taste very good, they were kind of stale. They were also a little too sweet.

I visited Yum Yum Donuts in San Marcos tonight, and while I was in a great mood, the service was really disappointing. The shop is open 24 hours, which is awesome, but the person taking my order seemed way too busy with other tasks to pay attention. I asked about teas and other items, but he was so blunt and distracted, just going back to his tasks while I was still trying to figure out what I wanted. I get that he was busy, but when a customer is standing right there, it should be about the customer. I hope they can improve their customer focus, because the donuts themselves were okay,but the service left a lot to be desired. read more

I had the Spanish breakfast sandwich wrap and it was so delicious. I didn't try any of the donuts. My son did and he enjoyed it. Good solid service. Clean tables to dine in read more

I went in today Thursday and the lady came from back and says hola and I say hi how are you? She was horribly rude from that moment on and why? Bad attitude and it makes the food tas horrible. Vieja con sangre pesada ni ganas de comer nada de este lugar read more

Very disappointed. This is our usual to go place and this is the second time we get stale donuts.

Wow this place was bad. The ladies behind the counter were rude to every customer if they didn't look mexican. Rolling their eyes, and didn't even answer any questions of theirs. Donuts were very dry, tasted a day or two old. Worst i've ever had. I would definitely recommend giving your money literally any where else. read more

Although this happened a month ago, I still felt I owed this review. I stopped in the morning to pick up donuts for my son's birthday, and they surprised us with some extra--so sweet! The service was wonderful, and we'll definitely be back. And the donuts were absolutely delicious, by the way. Thank you. read more

I got the chipotle everything bagel sandwich, and got turkey instead of ham, but the turkey seems to be altogether kind of like a patty and just doesn't look right I honestly was disappointed because it was nine dollars and was just not good. I don't blame the workers at all, but I do think that it can be lowered down to a better price and have better meat read more

Service was quick and easy! The donuts are well displayed and look delicious. Social distancing and wearing masks is enforced and the establishment is cleanly. Love that this place is open 24 hours! read more

The service is good. But the coffee is gross and expensive. The ice has a weird taste to it. And the donut holes aren't worth the price. I grew up eating the donuts from this place but now as an adult they don't taste the same and everything is overpriced. I wish there was a Dunkin Donuts around this area. read more

Poor quality food, very dry donuts. Got a sandwich and literally the first bite my stomach felt like I got gut punched. Way better donut shops out there read more

This location is a calm location, at least at the time I visited the donut shop which was 10:30am. The donuts them selves were okay. They are a little less quality donuts than let's say star donuts in San Marcos for example. The dough wasn't as fragrant and soft, seemed like they were there quite a while. The service was standard, Cecila, was efficient and straight to business. The place can use a little sprucing up, but if your in a rush and want something quick, this place is okay. read more

I will never go here again! I bought two glazed donuts and an apple fritter took one bite of a glazed doughnut. It was disgusting. The donut store is dirty. All the cases were full at 11 o'clock in the morning I Shoulda known better normally at 11 o'clock if it's a good donut shop they're empty I do not and will not ever recommend this place. I threw away the donuts they were gross. read more

Donuts are not good. Taste old. Also they are almost $2 per donut. My kids couldn't even finish their donut.

I called the store about nine times within about 15 minutes and the call was answered on the 6th time but then the call "dropped". I called many times after and never got a response. This location was 9 minutes away at the time. I drove over and it was empty, only employees working. When I got there to order since I had no luck calling: 1. They only had the option of a plain bagel and the onion bagel, no jalapeño bagel 2. They had no chocolate chip muffins 3. They had no maple donuts at all 4. No peach tea Snapple And keep in mind ... it was only 12:30pm Very disappointed read more

Best doughnuts in north county San Diego. I can eat their doughnuts two days later and its still good.

donuts are fuego. service was goated. super chilling environment yup read more

Yum Yum Donuts - i ripped out the bag you know me - Donuts Near Me - San Marcos, California

Nothing fancy or interesting. On par with VONS as far as selection and quality. The two stars is because my chocolate Old-Fashioned was missing a large piece (see picture) but they gave me it anyway. ugh... - The Yeast donuts are not very good. - Very limited selection of Cake donuts compared to the yeast ones. - While Pastrami on Bagels sounds interesting, its strong smell isn't the most pleasant thing when you walk into a donut place looking for donuts. read more

Nice late night dessert place and great service! Definitely recommend dropping by if you're in the area and want some good doughnuts!

Me and my bf come here for the sandwiches, which are pretty good. Customer service is straight to the point, which I like . Come in for what you want and out you go read more

They might have good donuts, however I wouldn't know since they were closed (at 11pm when I arrived). How are you going to advertise 24 hours but then be closed with the door locked? So I was very disappointed since I drove there specifically to get donuts and came back home empty handed read more

Yum yum donuts is an awesome spot for brunch! The pastries are so soft and well crafted. The inside is so clean and well maintained. The location is very central. Martha was working the register, she was very kind and took an interest in our order. We had two breakfast sandwiches on croissants, and they hit the spot! Her recommendations were delicious. This is a tasty and satisfying place where you will get quality pastries served with a friendly smile. Much love read more

There donuts are over rated. Service is not very good. The service is not good the entrance was hard to find so I walked past it and then I went back and the worker laughed at me. Over all they need better service and more donut options and a new recipe. read more

Terrible customer service by some of the staff. They have difficulty in basic math in figuring out how to charge for products that don't fit their mold. Don't try to order a donut that's out of their usual half dozen set and ask to be charged the difference; they can't figure it out and want you to order more than you need. Weird way to handle customer service when a customer simply asks to be charged more for the difference they are asking for, they can't tackle and are rude about it. Been coming here for years and other staff could figure this simple procedure out in the past. It's too bad their staff are not trained well these days. Won't be back. Wow. read more

These were o.k. But I've had better. Yum Yum Donuts tastes too sweet. After taking a bite, my throat felt like it was a sugar slide!!! And doughy!!! Don't think this is word, but it this is the word best to describe these donuts. A gulp of milk did not help. Mike went through the drive through so I can't give you any thoughts on the inside of this place. Donuts are sweet, sweet and more sweet!!! YIKES! read more

Damn thing is always closed till 3! It's supposed to be 24hrs! We have been there three times and each time its closed till three! That's not 24 hours! When I need my donuts this place let's me down. read more

Horrible. The lady serving donuts was coughing while getting my donuts and not wearing a mask. She coughed into my box two times. When asked if she had a mask, she said no. I declined service. read more

Horrible service, outrageous prices. Building & lobby is dirty. Go to the mom & pop donut stores, where they appreciate you.

This location has great service! Ruben was especially helpful and very friendly, which is great to see early in the morning. Thanks Ruben!

I went here because it was taking SOOOOOO long at Krispy Kreme in Menifee and didn't want to be late for work, I just Googled searched "donuts" and here I am., with a name like "YumYum" you would ASSume it would be, unfortunately I was seriously disappointed, the doughnuts tasted stale, not so fresh although they did have a wide selection and the lady behind the counter was very helpful. I would also think that today being Father's Day it would be ESPECIALLY fresh, not. read more

Mediocre customer service and a filthy customer seating area ruin what could be a decent local donut shop. Lord almighty do they need to clean this place and remodel the interior. It's nasty inside with glaze and grease all over the tables, chairs, floor, and just everything else. I didn't even want to sit down it was so bad, so I stood outside to eat my muffin. Do you know what bothers me the most about a dirty restaurant? ...It's wondering how clean (or not clean) the kitchen is and do I really want to be eating their food. This place will definitely turn you off if you care about cleanliness. Customer service is on the slow side, but in their defense, a lot of the customers seem to take forever to pay. Even with a couple of people in line be prepared to wait awhile. As for the food, it's okay. It looked better than it tasted. I would put the donuts and muffins above Vons but below Costco. The blueberry muffin was decently moist and flavorful, but the blueberries were very small and didn't appear to be fresh. Perhaps they were frozen or rehydrated? I'm not sure. Overall I would avoid this place until they clean it up and remodel...There are certainly better options in San Marcos. read more

Service was good. Donuts were not fresh they were also dry. I am not sure how often they bake their batches but it shouldn't matter. Selling old donuts is disappointed, specially because they're so close to me and i could've been a frequent customer... read more

Donut snobs this place is not for you. You will not find a Cronut! Donut Look, the donuts are fine. The selection is minimal but it has the basics. The donuts are no different than others in town. Customer Service The team behind the counter needs more smiles....but that is ok....they speak Spanish and hustle to get the customer in and out. Always remember to tip! Store I remember 5 years ago this place was dirty and disorganized. Now the decor is very well done. The outside is not impressive....but inside is amazing....for a donut shop. read more

I came in looking for donuts knowing afternoon isn't quite the best time to get donuts. Didn't like what I saw as far as selection went, but for a 24hr chain, you'd think they'd be on stock on some popular choices. Didn't have my favorite cruellers at the time so opted to try something else. Had the Tuna on the Parmesan Spinach Bagel. For $6.50 that's about the price you pay for any type of sandwich these days, if not more. The Tuna Bagel sandwich was pretty dang good! Would definitely come back to try the donuts whenever I'm in the area. read more
