My dad and I went on a Sunday morning to eat at this Denny's. It was a busy and a raining day. We waited about 10 minutes to be seated. Our server was Cynthia that provided the utmost customer service. She made sure our drinks were filled and food was taken care. The food tasted delicious and the coffee tasted fresh. I want to thank Cynthia for giving us a great experience at this Denny's. read more

Denny oh dennys. This location is one of those old school concepts with the chrome on the outside unfortunately the chrome doesn't look good once it's rains. Inside also is a bit run down but not a big issue . Service was good. The waitress was nice and welcoming . I was there for the buy one get one 1$ grand slam . Unfortunately I guess it's only weekdays but the waitress was able to redeem it for me since she didn't know that either . Food was ok nothing extraordinary. Typical eggs bacon and pancakes. Denny's is always a go to when you need something simple read more

Denny's - American Near Me - Rialto, California

Was gonna add a bad review because this was the worst restaurant experience I've ever had. But I feel like I'm just adding drops to an ocean considering this places terrible track record. I was in the area roughly around 2am because I'm originally from Anaheim and was looking to rent a room in riverside and don't own a car. As they reopened from their lunch break I came in and sat down, hoping to wait for the busses to resume. I ordered a coffee and was having some difficulty ordering food as I was strapped for cash trying to save for the room. As I talked to the waiter she became more and more agitated. She was very rude to me as I ordered and as I waited for my food she makes it very apparent to me how nice she is with the other customers, she was practically flirting with them. As I got my food, she takes my menus and I ask to keep them. I asked to keep them and she straight up just tells me "no" like I'm a whiny kid. At that point I take my shit and leave, I mean like storm out. The chef stops me and asks me to pay for the coffee. After telling him how dissatisfied with the service I was he lets me go. Hope this Dennys burns to the ground. read more

My family and I had an nice dinner, mostly thanks to our server, Debbie! She was friendly and attentive throughout our entire meal. She made sure our drinks were never empty and brought everything out promptly. Highly recommend great customer service! read more

On Thursday April 2nd, 2026. Me & my two friends were hungry for breakfast. Our two options in Rialto were Denny's or Norm's. We were talking and saying no matter what Denny's we have went to in the past late. The service and food was always horrible. So when we went to Denny's we got seated fast & our young waitress was really nice. We ordered breakfast and coffee. My food was perfectly done. My pancakes were fluffy, bacon was crispy, sausage just right, red potatoes cooked exactly like I asked and eggs cooked perfect. Coffee was as hot & freshly made. Our waitress was wonderful & attentive. Just wasn't to say thank you to the cook and waitress. I highly recommend this Denny's. read more

I recently visited this Denny's location, and I was extremely disappointed by the experience. During my meal, rainwater actually seeped through the ceiling and dripped directly into my food. It was absolutely unacceptable and very unsanitary. read more

Denny's - Choc. Chip Pancake slam (no Banana) (Background) Kids menu Birthday Pancakes - American Near Me - Rialto, California

My statement is from last year October 17, 2024. It was my birthday and I tried to get a grand slam then they said I had to fill out the email and I never got a confirmation whole time. The restaurant was smelling like rotten pee and the floors were wet, and I just did not feel comfortable being in the restaurant. read more

I've been going to Dennys for a while now. I like visiting new ones all the time. However this Dennys is the worst. My friends and I came in for an early breakfast at 5:40 AM. The service was terrible. We were sat quickly which was the only highlight of the mediocre service. We waited nearly an hour to receive our food. Like I said I've been coming to Dennys for a while, so I knew exactly what I wanted. My friends did as well. We ordered while they took our drinks. During the hour wait for the food. Two different groups entered the restaurant. They were taken care of. They received their food before us and before we knew it they paid and left before our food even arrived. read more

Service was quick and amazing! No complaints, food was good, prices were great, ambiance was chill, will be a regular!

It was a 15 minute wait @ 9:30 am Sunday. Our server was not the exceptional one. She didnt come back after just dropping of our orders without even bothering to ask if anything else we needed. She never smiled at us but she was friendly and smiling to othe customers who were Spanish speaking. We had to call another waitress to get us a container for our leftover. I was planning to get some dessert but just didn't want to stay any longer. Ambience was too loud by the kitchen window and their order pick up counter. One server was loudly complaining about her break time hours. Food and service is not bad at all. Redeemed the free grandslams breakfast reward from TMobile Tuesdays. Pancake is chewy like i love it but needed some flavor it was bland. Eggs were perfection. read more

I have been to a few breakfast spots around the area and non can compare to the best customer service I was received by my server Debbie she was in such a positive/outgoing mood. Very attentive to our needs as customers. The Christmas music was a very soothing touch to the atmosphere as well. Overall great experience Debbie deserves a shoutout for her hard working ethic. read more

I order 2 bacon avocado cheese burgers and paid $57 dollars and no bacon and no cheese on my burgers.

This place is trash they forgot my food and still didn't wanna give me anything for free. Do not eat there. They are rude and don't even want to help you. They gave me a coupon for 20% off after they forgot my food. This place is horrible. read more

Parking: Plenty available! Ambience: Came in the winter, so there were some nice Christmas decorations around :) This is the first Denny's I've seen with the classic exterior layer of stainless steel siding that's standard among American diners. Service: Quick and friendly! Taste: I got the Classic Sampler, but asked to replace the mozzarella cheese sticks with more onions rings. Onions rings and chicken tenders were pretty good! My go-to has always been the Supreme Skillet, but they no longer serve that, so I settled for the Santa Fe skillet, which didn't hit the same :/ There was also so much oil that was used that there was a layer of grease on the bottom once I was finished. Also got the green smoothie, which was a bit too sweet and tasted quite artificial. Overall, was fairly disappointed as Denny's used to be my favorite brunch spot, but it didn't taste quite the same this time around read more

Pricing is out of control might as well go to a local restaurant spent 25$ for a decent meal

Absolutely horrible service the worst I've ever had been here over 10 minutes still have not gotten even asked us if you want anything to drink two people served before us read more

Place is clean we came on a slow day in the week but our server Deborah was very attentive and nice food was great

It has been a really really long time since I've had this horrible customer service at a restaurant... Let's start the Kids high chair Was literally disgusting... I watched them clean off the table without Moving the condiment tray And just left the food particles under it.. We waited 35 minutes Appetizer let me remind you there wad only 4 groups of people in there And then. . which I cannot stand they brought / Served meals Not together and at separate times you go to restaurant to sit down to eat together As a family . My husband got his meal first then they brought my sons and they brought my other son meal and I was lost.. So everybody was done eating but me and I felt hurried... They never came to refill our drinks I had to go to the cashier to ask... It was just horrible never again will I go to a Denny's restaurant... We spent over a $100 not to eat a meal together read more

The Service was horrible took a long time and the food was horrible as well. We will NEVER go back again. So disappointed

My family enjoyed ourselves so much!!!!! Moons over my hammy what so so good, very tasty and this Dennys did a very good job! Our waitress was amazing and always asked if we needed anything and the tables and chairs was all clean! The environment was amazing very diner like feel! read more

Good afternoon! My boyfriend and I went this morning to get the All American Slam, buy one get one for $1 and ordered two coffees. The bill came to $45! I asked what happened to the buy one, get one for $1? The cashier said "oh, that's only during the weekdays". I didn't see anywhere online where the special said weekdays only and neither was it posted at the restaurant. I did see where the special said "dine in only". If it's weekdays only, then please state it somewhere. I wasn't expecting to pay $45. I was expecting a bargain on a special. I won't be going there anymore. Now I spent $20 extra I didn't have to spend. False advertising at it's best. read more

The service last night was phenomenal! Our server was training someone and whoever this guy is he's definitely the right guy to be training new servers. He was understanding and funny and served our party of 11 as if it was his best friends. The food was amazing and he offered to split the check up before we even had to ask, which we know it's sometimes an inconvenience to do so. Restaurant was relatively empty but it was 10pm but it was immaculate and clean! Who's ever managing this location is leading their team well... great job! read more

30 minutes sat before order taken, 30 minutes later and not even our drinks were out. My party of 3 came into this Denny's last night late right at midnight, it's a Friday night so we anticipated some wait... we were beyond disappointed by the experience at this Denny's. There were about 2 larger groups of at least 7 people who were keeping the staff pretty busy, but we watched as the group seated right next to us received their food and then finished and left before we even had our order in! When we finally placed our order, nearly 30 minutes after being seated, we watched as other small groups would come in and be seated. These other small groups were getting their food before us! 30 minutes passed after placing our own order and not even a simple few drinks were brought over to us. When we asked a different worker, not our server, if our food was even started yet she told us no. Nearly 30 minutes waiting to place an order, and 30 minutes later not even the drinks were at our table of three! We told them we were leaving, and we went to Norms all the way in the Renaissance shopping center and guess what? Despite there being more people dining there, and an almost equal ratio of staff to people compared to denny's, we were sat almost immediately; our order taken almost immediately after being sat; not even 4 minutes after ordering we had our drinks; and not even 10 minutes after ordering they had our food on the table! It took us longer driving to the Norms than it did to get our meal once there... meanwhile this Denny's had us there nearly an hour for absolutely nothing. An extreme disappointment. read more

Food was decent, but the service was horrible, missing food that was ordered, not how we wanted it and had to wait while family ate their meal. Waiter took forever to see what we needed while she was talking to other co -workers, mind you there was only 3 other families waiting for service also while she was talking away read more

Burger that I ordered was way to sweet and the chicken tender I do not recommend they are so salty and dry

Upon entering the establishment I noticed the flooring was very nice and clean. The tables were clean, durable and aesthetically appealing. After being greeted, we were offered a table by a waitress with the name of Yoli. She was very cheerful, cordial and warm. With her greeting, she offered us drinks and let us know that she was going to return with the menus. The food was great & full of flavor. The coffee was hot and at the right strength. She was able to provide a non-dairy creamer. Upon leaving, I asked for a courtesy cup of ice which came in very handy since the day was already hot. I shared my gratitude with the manager. read more

While we understand times are hard, there's staff shortage...etc... there's no room for rude. Walked in saw several online orders come in and out. We're told 40 min wait, waited. Woman at the register and behind counter moving orders had a horrible attitude. Anyone that walked in was told 30/40 minute look at all these ticket (online orders) As we sat Waited patiently we over here her tell what I'm assuming is the manager "I will seat them but will not take an order." That is All we needed to hear to walk out. If this is primarily online or that's what they prefer cater too that is totally understandable but should be stated. Waiting is one thing but to wait and be attended with such poor demeanor is not worth paying for. read more

Wow can't believe this we drove miles away for us to get no service because she had to go lunch how is that fare to a loyal customer? Very disappointing from dennys on quality control and thinking this was 24hr service not cool read more

Had to walk out due to the hour wait everyone was complaining about and not only this but there is nobody attending the front desk, there's no way to tell what's going on when you walk in. Apparently there's a clip board somewhere up front on a desk where you put your name down. Honestly the worst first impression, I don't understand why people put up with poor customer service. read more

Terrible service the waitress rolled her eyes and gave lots of attitude. It was very hot inside and everyone was so negative. The food was mid nothing special and it took forever to get here. Don't come to this dennys read more

ordered take out. food is good but forgot items that i payed for , (fresh fruit) and (ranch)

Like wtf horrible service. Just save your coin and go some place else Please AVOID this place at all costs We waited like idiots. 45 mins later nothing. We left horrible service. Horrible experience read more

Service is just alright, but food was all correct and had nice presentation. The reason I took off one star was because the waitress at the front gave no greeting and let 3 groups of people accumulate in the lobby before telling anyone we had to sign ourselves in on a clipboard on the counter. And no, there wasn't a sign and it was facing away from the customers. The other waitress that took our to go order was nice, though. read more

Came here around 2:30 am to pickup a delivery. As soon as I walk in I'm told no pickup orders are ready and it'd be another 10-15 minutes, fine I wait. 20 minutes pass I go inside and am told the cook (the only other employee present) is on break so it'd be the aforementioned length of time again. Ok uhhh sure. Wait the time again and go back and am told they don't have the bread so I couldn't get the order.... Mind you I haven't even told the Middle Eastern (I think) lady at the register what I was there for so when I do she repeated what she said and I ask why I wasn't told this beforehand and she just stands there... now I'm going to be as honest as I can. The employees here need to be tested for drugs because the lady taking orders at the register looked like she was in orbit. I would advise against eating at this location if the employees are as baked as she was read more
