Ok look the food is good. That's not why I gave these guys a one star review. I ordered a meal that had included toast. I did not receive toast. Small trivial toast. But I paid to get what I ordered: the whole meal. It is a principal issue. I paid for it, I should get it. So I called grub hub customer service, which was very helpful; The representative I spoke to called both the driver and the restaurant. The driver said he left everything for the order outside my door. The bag and the food were neatly arranged, sans toast, when I got them; It did not look as though somebody had gone rifling through my order, pilfering toast. The restaurant claims the toast was with the order. I did not ask for a refund. I don't want one. I wanted accountability, someone at the restaurant taking responsibility and saying 'yeah oops I made a mistake I forgot to put the toast my bad.' Simply because I paid for it and I want some acknowledgment that you don't just take someone's money and not give them what they pay for. Needless to say I will go to a different Denny's next time. read more

Stephanie gives amazing service! Her upbeat personality, happy smile, and attention to detail was off the charts! She really put all of us in a great mood! She is the definition of hospitality at its finest! Give this girl a raise! Thank you again ! read more

You should definitely ask for GABBY!! She deserved her tips so bad...! Always paying attention to you and asking you frequently if you are doing okay, if you need something else or giving you details about the order you want Please! Must ask for her read more

Forget Miami Beach, this is the hottest Denny's in America. It's not just the bumping music in the kitchen or the insanely attractive staff, but our high-maintenance special order was cooked to perfection. Do yourself a favor and accept your Moons Over My-Hammy from no lesser place because the folks at the Rancho Cucamonga Denny's are serving more than just food. read more

The business owner posts pictures of food that is nothing short of perfection and looks mouth watering delicious. Opposite of what is actually served to the masses. Hate when they do this read more

Surprise! Denny's has the best burgers in Rancho Cucamonga. I've tried, I believe every burger place here and they win. I only gave them 4 stars because I always ask for the toppings on the side and they always have to remake the order. But I don't mind because it's always fast, the staff is nice and the cooks are good. So what's an extra 10 minutes for the best burger in town. read more

Food is good...service needs improvement. Starting with management. Definitely changed over the years.

Who doesn't love Denny's. Well, if you're hungry at 3a.m. Don't bother with this place. Went a few nights ago at 3 am and was told the cook was on break so they can't cook our food. The waiter told us we can stay if we want to wait. Then he told us they don't have a manager on duty at that time. Fast forward to last night. My friends go for a late night dinner. They actually had a cook that night. But before the food arrives, they have roaches crawl on the table. When it was brought to the attention of the restaurant, they said they know about the problem. People trust that this is a clean establishment and bring their families here. You guys should be ashamed. Get a manager at night and hire 2 cooks. Or does the owner not care??? Either way. I will never be back here again. read more

Worst meal I've ever had. I can't believe how bad it was. I got a bad egg over easy. Yolk was a strange color. Looked rotten. Got all over the rest of my food. I asked for replacement. Waiter took my plate and returned with one egg. They could replaced the uneaten bacon sausage and hash browns. I had to go somewhere else to get a real meal. read more

I really never go here but my boyfriend was searching for a patty melt. I went in and placed a to go order. The patty melt came with fries but no drink. It costed $15.00 which is very pricey for a Dennys meal. I had to wait 45 minutes for a single meal to go. I can't believe it took that long. It wasn't even that busy. People were being seated very quickly. I would have probably gotten my food sooner if I was staying. I guess to go orders don't matter to them. I will not be coming back. There are better places in this city that cost less and will definitely not take that long. read more

GREAT outdoor seating experience. I came around 8pm on a Thursday night and the weather was nice, and the restaurant wasn't too busy. The dining area was set up in the nice walkway outside. Felt very intentional. Our waiter was very attentive to us and made sure to check in regularly. Bathrooms are open, masks are worn by staff, sanitizer provided. read more

Shoutout to Joe! Literally the funniest and most charismatic server there ever was! My friends and I piled into this Denny's at about 1am and two of them were drunk. The Denny's we normally go to in Redlands has very bad vibes and we can tell the wait staff hate us. This Denny's has such a great environment. Everyone who works here is kind and sociable and hilarious. Such a great atmosphere! Joe was our server and he wowed us with jokes, impressions, and quick remarks. I love a server who isn't afraid to clown around with diners. The food was also impeccable but that goes without saying. I don't normally give reviews for chain locations but I felt so passionately about this experience! read more

Was sitting at a table for 10 minutes and did not receive any service. I went to let them know and one of the servers didn't even look at me and just dismissed me. My son and I left. read more

I really like the location of this Denny's because it is close to Victoria Gardens. The food was served to us hot and fresh but I was kinda disappointed how I can't get banana nut muffin instead of toast because they let me do that in BC CAFE. I enjoyed my ULTIMATE OMELLETTE with hash browns. The service was nice and efficient. Our food arrived on our table on a very reasonable time. I will definitely go back to this Denny's because I LOVE DENNY'S! SIGN UP ON THEIR WEBSITE AND THEY WILL SEND YOU 20% OFF COUPON ON YOUR EMAIL. --i love to save read more

Steven the shift manager literally js the reason why this restaurant flows so well! He is on top of his game! This dennys would not be in business if it wasn't for the hard work and dedication to the guests such as myself that come in! I hope that the district manager sees this and gives him major recognition for his commitment to Dennys!! read more

I order breakfast from here and it's always warm & delicious & delivered on time. Couldn't ask for more.

Awesome service, great food, William are server is excellent at his craft, provided excellent service, I would definitely recommend this place to anyone and would definitely be coming back to this restaurant. read more

This is a one star towards the owners of these restaurants Especially the owner that owns this location and the location in Ontario Mills...yes he owns both restaurants If you turn on the TV and you see 599 super slam and then you walk into these restaurants and they charge a dollar more... that kind of gets you upset? In these trying times.....U would think these restaurants would try to please the customer at all costs?? So when I get to this restaurant I tell the person that super slams on TV or 599 and she's like we cant override the system...it's 699....that's just pure BS and then I told her that if I go down to the Ontario store they're willing to do 599 for the same breakfast...... And then she looks at me like she doesn't believe me or I'm lying or something... All in all it comes down to Customer Service.... So again this is a request for franchise owners to stop gouging customers for just a dollar more??? read more

Always a good place to come during the wee hours of the morning. The music selection is on point, food is good, and service is professional, and fast. read more

See all

So, we had a horrible experience the first time we visited this Denny's location. Long story short, we were never supposed to come back. For some reason we decided to give it a second chance and I'm glad we did. Our server Mark G. Was awesome. We could see him keeping the entire place clean and organized. Every request we made was taken care of instantly. He is doing even more than he is supposed to. Staff feel like they're happier, more proactive and nice with the customers. Food was great, it was served quickly and everything tasted perfect. Good job, Denny's. Good job, Mark and the rest of the staff. We'll be back. read more

If I could give this restaurant 0 stars I would. I went here after Easter 4/17/2022 and the service and employees behavior was ridiculous. The employees, which I am not sure if they were employees because most of them were wearing regular clothes, eating while serving food and yelling and cursing, had their children that we realized which were under 5 years old sitting in a booth by themselves. Also, when we left all of these employees and possibly friends of the employees were outside smoking and eating and going right back into the Denny's to serve food. I have never been to a Denny's with service this bad. I will have to contact the heath borad about this particular Dennys. It was that bad. read more

Dennys: 2 eggs, hash browns, toast, coffee, coke = $16.97 (have receipt as proof) Farmer boys: French toast, 1 egg, 2 bacon, coffee, hash browns = $10.10 (have receipt as proof) Can someone from corporate please tell me why your food is 70% more expensive than a family owned franchise for much less food? The eggs I ordered were dangerously undercooked with raw egg, and the hash browns had about 4 teaspoons of salt mixed in. I will never return. I payed over $20 just for myself (with a tip) for this nonsense read more

It's been a while since I've been to a Denny's and in general it's not my favorite place to eat. But this location has amazing service and all the employees are so friendly! Huge thanks to our waitress Brittney very attentive, my family and I enjoyed our meals very delicious. They also had a balloon artist going around making balloons for kids with no charge tips complimentary. read more

The service was amazing Steve is an amazing server. He was handing the patio by him self.. thank you Steve food was good too

I enjoy coming , love the hours. Today's visit was not the best. Server took to long in all aspects From greeting, taken order, serving Our food, silverware. Place didn't feel clean I was not happy this visit. read more

I'll start by saying it's a Denny's, what do you expect. I've ordered food from here multiple times, always order the same plant based burger and every single time, they give me real steak. It's inconsiderate and disrespectful. When I've addressed them about how my order is incorrect the staff gets argumentative. Staff has no customer service even when they are in the wrong. People, especially the staff at this Denny's should be more considerate and careful with food, you never know why someone can't eat something. read more

This Denny's is literally the only "24 hour" eat-in place around.... so there are times when I want to go at 3am. The reason for the low star rating is the inconsistency with the times they close to "sanitize". Depending on who's working, it will either be 2am or 4am or who the hell even knows? They let some people stay inside and sit down and continue eating, but it must be their special friends only. Quit blaming your bad behavior on Covid! If you're going to close for cleaning, that's fine I get it. But closing at 2am, right when the bars are letting out (yes, they're open again) is a lame duck move for the only place open for people to go sober up, whatever. Once everything opens up 100% and night owls once again have a choice, watch this place go right down the tubes again. read more

Omg where do I start, awesome service yay !!!!!! We came in on Monday at 5:30pm which was very lonely which was good since this location tends to be crowded at times, the waiter was very attentive and kept them refills coming, the food was very good we really enjoyed our dinner. Will be returning for sure! read more

Horrible service, under staffed. Their was one server who was taking orders, picking phone orders and checking in and out. The family next to us just left. We have tried this place twice by now each time short staffed. Serving food like they are doing a favor to bring a refill on drink. Will not go back read more

Service was horrible need more workers spent 2 hours just to receive our orders seriously get more help never again eat here

I walked into this Denny's like anyone else does, not because I wanted to go to Denny's but because it was open and I was hungry, I walked in and was greeted by a man in the front who wrote down my party's name, it was pretty busy for 11 at night but after a 20 minute wait we were seated and greeted by quite possibly one of the best waiter's I have had the pleasure of meeting, his name is Justin and he was quick to help and answer questions about the menu, even going so far as trying to help us with an order that was removed from the menu years ago, he was incredibly kind and helpful, every single person at my table enjoyed him and his helpful service, if he was there to greet me every time I walked into a Denny's I would eat there more often read more

Food was pretty good but the service is spectacular special names go out to STACY AND YOSHIO they're serving somehow makes the food 100x better and the stay is amazing I feel so at home! read more

Lol this place is a joke during the graveyard shift!don't come here unless it's your last resort. The waiter turned us away because he was on his smoke break and by himself.(literally cigarette in hand when he told us) OK! Now that's not on him but on management for understaffing-- but the teens of this town seemed to have taken over the dining room and parking lot lmao drunk and all! but what can I expect from a small town Denny's when it's the only thing open ‍ read more

This is the best ran Dennys I've ever been in. If you knew my wife and I you would know we are not easy to please when it comes to resturants or fast food. But this place was amazing. Not only was the food great and the service but this place was packed and we were in less than 15 mins. There were like a well oiled machine. There staff was friendly, fast and very efficient. No food was sent back nothing forgot, cooked they way we asked. The waiter keep are drinks full. Even felled of extra napkins before I asked. Most places I will end up going and asking someone for them because I get tired of waiting for are server to come by and check on us. Anyway the place was fantastic.... read more

This is the perfect location to go to if you want a fast, friendly service. However, it's not for families. All the girls are dressed in skin-tight black jeans or leggings. Mostly leggings with body suits or crop jackets/tops. Some of them are sheer leggings. Quite tacky. Booty pants now, booty shorts next, I guess. read more

At first I wasn't too sure If I wanted to stick around here after waiting over 15 minutes to be seated.There was plenty of seats and booths available but the manager was distracted.After being seated we had the best service by our waitress Cassie.The food was delivered fast and very good.The bathrooms had a fresh smell and were clean. read more

We decided to go for a bite around 10:30 on a Friday night and this place was packed, yet we were seated very quickly. Food was what I expected- tasty, hot a visually appealing. Thanks again for great service. Mike read more

All I can say is whoever the young Hispanic woman with the blond highlights that you have as a greeter in the morning needs to learn some form of customer service or get a personality transplant. Very unprofessional and downright rude. read more

So for starters, we've been coming to this place for years but it's BEEN YEARS since we've came here. Went back with my partner for a lil date to get some grub & our waiter had the audacity to make me feel bad about getting a shake & chicken tenders with pancakes on the side. He kept making unbelievable comments about it all & then when we asked him where the pancakes were he said he "forgot to grab them" but then I realized he just didn't put in the order or forgot to so he came back n was asking if I'd much rather just cancel them since I "DEFINITELY don't need them". Lmao he kept making unnecessary comments the entire time with weird faces. It was beyond me and my man didn't appreciate it one bit even tho he laughed n realized damn, this dude don't have no filter or common courtesy. We left zero tip. Food was mid at most. I understand it's busy w/ graduations etc but this was no excuse. Y'all should fire someone like that. 2 stars. read more
