Bitter sweet experience. Long story short, it's my wife's birthday and we were looking on enjoying a grandslam and ordring a few appetizers. Fifty One minutes later (yes - 51 minutes) our grandslam entree was delivered to our table... minus the appetizers. So, what's the point of an appetizer when it goes after the meal? We do appreciate that David, our server, sent us off with extra seasonal fruit and that the grand slam entree came with a scoop of strawberry icecream. So we got to thinking how Denny's can make this experience better. And I can't really speak for Denny' in general. The Denny's in Brea was much quicker, busier, and well staffed. So to speak strictly about Denny's in Fullerton, doing these things will greatly improve their service: - Hire more people! Kill those wait lines and earn a profit to boot. David said that we are in some sort of queue and that mobile orders are in the queue as well but with more staff, that shouldn't be an issue anymore - Check up on your customers. We had to go to the servers and ask when the food will be ready. Basic customer service. You don't put your customer on hold on the phone for over 2 minutes and you shouldn't make your customer wait more than 10 to 20 minutes without giving them an update. - Give some sort of compensation. Granted David gave more seasonal fruit and the strawberry icecream was a nice gesture. I'd add half a star more but Yelp won't let me do that. So Denny's of Fullerton, if you are reading this, we are willing to give you another chance. If you can give us an entree on the house, we can audit the Fullerton Denny's and increase those stars if we see improvement! read more

Food is always good, and Isel was an awesome server! She was super nice and made sure we had everything we needed. Thank you!

David was great!! service with a smile and rest of staff was very friendly too, the experience was great!

David was our server and he was super nice and had awesome service! Would deffff come back just for him

So let me get down to it. The services was very sub par and very lackluster. I get being at work and having a long down but that's the services industry.There food was made with no love at all. The eggs in the omelette where simicooked, the over middle eggs where runny as all out door, the streak was not fully cooked. You can just tell this was thrown together read more

I really like this Denny's over some of the other local locations. Our server, Sarai, was great, the breakfast was very good and hot, she made us a fresh pot of coffee, we even noticed that we liked the music more! This is our new fave Denny's! read more

Delicious food and our waiter Luis was friendly and constantly checked on our table! Great service and food! Thank you Denny's

It was 4 AM and I was nodding at my table but was told immediately and rudely that I could not sleep there while there was someone sleeping there from I stepping into the store until I left one hour later, I failed to understand if they were acting this way to me because of my race. I am giving it two stars because the lady in the front maybe saw how I was treated and offered me some water to take with me while I was waiting for taxi. read more

Delicious food, and close to the school. My server Andrew was very helpful and attentive

This Denny's is next to CSUF so there's always a bit of a wait. My bestie and I went for breakfast and waited about 10 mins. Not too bad. The waitress was very nice and helpful. We ordered off of the value menu so I got the $4 breakfast of pancakes, scrambled eggs, a sausage and a strip of bacon. It was yummy. My friend got the $6 biscuits and gravy with eggs and hash browns. Hers came with 2 drinks so she gave me the coffee and had some orange juice. Overall it was a good time at Denny's and the wait wasn't as bad as I've seen elsewhere. Plus the staff is cool because they're mostly young college students (like me and my friend). read more

Great service and the friendliest staff! Luis was our server and he was wonderful. Thank you!

We chose this restaurant because it was convenient to our hotel (Marriott). As I parked, I noticed it was next to a Hilton property too. The place was spotless and even as we sat down, I noticed a gentleman mopping the floor. We were seated immediately and from then on, we enjoyed 5-Star service from Juana G. Juana did not hover or rush, yet she was there for every little request (waters, hot sauce, extra butter, etc.). She also kept our coffees topped off. Amazing service to an excellent meal! I had the 9-Grain pancakes w/avocado and it was delicious! I haven't been to a Denny's in a while, but I'll keep an eye out next time I'm looking for breakfast! read more

What an awful experience. Sandra doesnt deserve to be a server. Forgot food, took forever, never brought refills. Avoid this denny's. read more

I went to Denny's and David was our server, he was very friendly, polite, and enjoyed him being our server..

We went to Denny's twice . David was our server very friendly, polite, and good service..

I'm not a big fan of Denny's but my lady friend wanted a quick semi healthy breakfast. Everyone waited on us. One took the order and three different servers brought the food out. It's Denny's, everyone knows the food isn't the greatest but for a quick meal with friendly servers, I'd come back. read more

Love this restaurant! They treat you like family. Gaby, our server, is always pleasant and efficient. She makes sure our order is exactly what we wanted. The management is welcoming and helpful. I really feel cared for at this restaurant. (Plus they are always cleaning something!) read more

David was our server and he was absolutely amazing. He was constantly coming back to our table to check up on us, GREAT SERVICE

Excellent Service ! team work among service crew, Alex & Co. is very very good. love to comeback anytime... read more

David was our server - excellent service and food! David was attentive, polite, and professional. And this Denny's is open 24 hours!

Again Denny's is like the burger chains and can be redundant for reviewing. So this is mostly a reboot of the last Denny's I reviewed. Everyone knows about Denny's food -- it's pretty much a hit or miss. It's Denny's, so you know what to expect. I was meeting a client for a breakfast meeting. I believe I was most happy that the service was fast and friendly and they had hot bold coffee. The restaurant was clean, the server was friendly and attentive and the food came out quick and hot. I enjoyed it. I had the American Slam cheesy scrambled eggs, sourdough toast with extra bacon, no sausage... no likey Denny's sausage. My dealer just had eggs over easy and toast off the seniors menu. yawn this was a spacious Denny's too looks pretty new. As always If you're hungry and want something simple and filling, it's a great choice. read more

Denny's - American slam - American Near Me - Fullerton, California

Awful place. Terrible service: took 10 mins to get drinks and people that came in AFTER my party got their food BEFORE we got our drink order taken. Terrible food: barely warm, bad tasting. Stay away! Go to iHop or another Denny's. read more

A lot of my friends has informed me that Denny's has really stepped up with their menu. Well, I decided to try it out tonight and man, it was delicious. I got the Bacon Grilled Chicken sandwich and boy was it yummy! Definitely one of the best Chicken sandwich I've ever had. So as usual, after my meal, I need desserts. I had the cinnamon pancake hush puppies and the apple crumb pie a la mode. Both of them were equally delicious. It's a matter of fact, I think they are better than most of the big chain restaurants, but for less than one tenth of the price. Of course the superior customer service doesn't hurt. Our waitress Janet was super friendly and got my special orders (both my sandwich & desserts) perfectly made. The place was clean and the price is most certainly reasonable. I have a huge feeling I will definitely be back very soon. Price: 5/5 Quality: 5/5 Customer Service: 5/5 Cleanliness: 4/5 read more

Terrible service today. Wasn't even acknowledged after coming in since they were so busy. They don't care because they know others will come. Won't be back to this location anytime soon. Sorry! read more

I woke up early and was there for breakfast at 3:30am. I was fine with their mellow Christmas music. Then the two drunk people decided to play their club music through their phone loud enough to hear at least halfway across the restaurant. Eventually I asked if they'd turn it off. They asked why. I said because they already had music playing in the restaurant. They ignored me. The waitress didn't do anything, so apparently at Denny's you can bring in your own music to play. They brought my food. I ate a single bite, then decided that I wasn't going to pay 20 dollars for this. I left, telling her I didn't want to listen to their music. Outside, the security guard started screaming at me as if I had just viciously attacked someone. He told me to pay. I sat down, but by then, after the way the security guard had treated me, I had lost my appetite. They allowed me to leave without paying (I still hadn't eaten anything more than a bite) and they said I was never allowed back there again. read more

Straightforward classic American fare. It's nothing special, but at least it's open 24 hours a day and most of the staff here is pretty nice. I did have a weird encounter where one of the waitresses tried to swap out my food with someone else's after I had already bit into it because she realized she had mixed up our orders. Definitely alarming! Overall, the food is greasy, but reasonably priced and parking is plentiful. Come here on your birthday and get a free grand slam if you show your ID...wahoo! :) read more

Marisol is the greatest server, we love her!!!!!! Been coming to this location for years and the staff here is great. Always a good experience thanks to the awesome staff. read more

David was an excellent server, made sure we got everything we need and very sweet. My fam and I will forsure be back when we have the late night munchies read more

Came in to order to go. Waited 30 mins and asked for an update and they told me they were preparing it. 50 mins go by and the manager asked for receipt and they start making right there and then. This is the second time this Denny's delivers the worse customer services I've ever received. My first review ever and it was just because of this horrible experience. read more

Wonderful blueberry pancakes that are fluffy, flavorful and are delicious without a need for syrup. I can eat them plain and they are AMAZING. Thus location in particular is our favorite family spot as everyone has a favorite dish. It's also a place that has been with us through all kinds of life events as a comfort to us. Kind of funny that a chain restaurant can hold that kind of place for a family but we have great memories. One year we went to this Denny's for Christmas Eve dinner because our oven failed us in our new house. Denny's was open and it was a lifesaver! After that year it became a family tradition. Lol It's also been with us throughout the Pandemic and provided ongoing special event dinners during this last year. Keep up the great service and excellent food. Thank you. read more

What is this crap? I ordered for delivery and this is what i got. Very bad, everything was salty and disgusting. Waste of my money and my time. Where is the manager here? read more

Denny's - What is this???? - American Near Me - Fullerton, California

Had to fix the review; been to too many Denny's lately. This one was actually far nicer than the other one we hit (see Denny's in Artesia). A reasonably quiet Monday morning as we prepared to trek from the hotel to Disneyland, and just after being informed by the nice Marriott people that the breakfast heavily implied on the booking notice was merely that (the notion of breafast was merely its availability, not that it is included with the price... sneaky). But not Denny's issue. We were seated promptly, the server was attentive, and the orders came out as we'd expected. In and out in a reasonalby short time and on the road to harrass a giant mouse. Good times! read more

Diane is amazing with such good customer service. I ordered for my family and there was an issue on a delivery service website and she went above and beyond. Made my day!!!!! read more

Ordered through Grubhub. Had breakfast meal and a chicken entree. Chicken entree was great, but the breakfast was another story. I ordered chocolate chip pancakes, but the pancake itself taster like old Blueberry Pancake Batter. Very inedible. That being said, the sausages tasted funny. Like if someone had sprayed cologne on it. Sucks because I normally love Denny's, but I was just severely disappointed this time read more

Great food and just a good place overall for a late night grab. Server David was so polite and helpful! Definitely going to make this a regular spot. read more

Came here about 10:15am 1st sign of problems: doesn't even deserve a 1 star: 1. I was waiting to be seated and the hostess seated the just arrived and I told her I was here first. 2. I noticed they took care of the other families first from getting the drinks, ordering even though in the beginning I told them I was their first. 3. Took the waitress a really long time before coming to get us our drink and food order. 4. After ordering our food I told the waitress what we needed which is steak sauce, Tabasco, extra napkins, extra butter and she said as soon as our order comes out. 5. Our order came out and even asked for orange juice for my daughter took another 15mins for steak sauce, Tabasco and butter to come out. Almost at the end of our meal still no kid orange juice we asked again. She came back and said this on the house. 6. We were done we asked for 2 boxes, we already paid and everything still no to go boxes waited for 15 mins just to get it. Please have management read the reviews to do some changes. This is very unpleasant experience. read more

This place is terrible! The manager has given my takeout order to someone else. Who the fuck does that?! And then she keeps arguing with me about someone else picked it up! How the fuck is that possible when I am just walking in right now! The lease you can do is fucking apologize and compensate for my fucking time since I had to wait all over again for my food. What the fuck is the point of putting a take out order if I'm going to have to wait for it when I get to the restaurant. How idiotic! Honestly! It's one thing to make a mistake but she should have apologized and tried to offer me some kind of costumer service instead of being so insincere and un sympathetic. If you want to be treated like your the one that lost your order and deserve the attitude for it then please welcome yourself to this place. Ps: there were 3 other people who was in the same boat as me. I waited for another 30 min in the hot restaurant. Blows my mind away that there was no air circulating in that place. I felt so bad for the workers who were cooking in a hot box and mind you this place wasn't next to a beach. This is in Fullerton. It was 86 degrees outside. read more

Bar far the best service I've ever gotten at a dennys. My family and I cane for lunch and had marisol as out waitress and she was so friendly and made sure we had everything we needed and I can't forget to mention we're those kind of people that are picky and like our food a certain way. I ordered mozzarella sticks which were nice and hot and yummy . Next I ordered a buffalo chicken sandwich which is not on the menu anymore but i substitute it with chicken tenders and it was still yummy. The restaurant was clean and service was fast . I love this location read more

The first time getting together with family since COVID19 "stay at home" order was lifted. We chose Denny's because they offer something for everyone! We called to confirm they were seating indoors and that they could accommodate our large party. From the moment we walked in, the entire staff was attentive. They were following all safety measures and the food was great! Thank you to all for working and providing us with a much needed night out with family! Lots of laughs, yay!! read more

Love the staff and food is always fresh. Clean restrooms and staff is always friendly towards my kids. Keep up the good work guys
