I've been showing up to this Denny's as of recent to grab a bite while doing a late night homework sesh with a buddy of mine, so we were always there during the graveyard shift... the food was good, and our waitress Crystal always made sure we had everything we needed for the long night of studying! I really appreciate the care and joy she puts in to serving us, especially considering that it's during the graveyard shift! read more

I haven't been to Denny's in years! Their menu options have changed since then, but still have some of the classic Denny's dishes. My family and I were here at midnight last Saturday. Parking was easy - there were plenty of spots open in front of the business. Inside, there were a few groups of people occupying some of their booths. Our waitress took our drink orders right away and gave us a good amount of time to look over the menu. First thing I saw was the steak and eggs, SOLD! I noticed they served T-bone steak and eggs and Sirloin steak and eggs. I opted for the sirloin (medium-rare with grilled mushrooms on top), over-easy eggs, hash browns, and no toast. Our waitress offered pancakes at no charge, WHAT?! I was eyeing their plant-based pancakes, so I asked what was in them. Flaxseeds, wheat, and cinnamon. Mmm... Our dishes arrived all at once after a few minutes. We were all digging in and having a great time. Our waitress was lovely! She was attentive and friendly. She made the experience more enjoyable. I appreciate the fact this is open 24/7, and that the food was decent even at a late hour. Next time we're looking for a late night bite, I would come back here. read more

Everyone is working hard to get people seated, but Liz is our server. Great job Liz!!!! Thanks for great service for me and my lil son. read more

This review is based on tonights dinner. Thanksgiving turkey dinner was on the "salty" side. Even the steamed broccoli was too salty. I needed a lot of water to wash down the saltiness. If you come here, tell the helper to caution the cook not to put too much salt. There's table salt anyway. read more

My wife and I enjoyed having breakfast here with Liz as our waitress. Liz has been very helpful and always given us excellent service even when she used to worked at the Pomona Denny's. read more

Hit the spot for a midnight snack, but noisyStopped at the El Cajon Blvd branch at 1 AM since they are open 24 hours. The pancakes were great and the parking lot had plenty of space. The main issue was the atmosphere--the dining room was loud, messy, and several tables around us hadn't been cleared off yet. Average late-night diner experience. read more

This Dennys is super professional, super clean, and super friendly to all of their customers. First of all, today is Easter, so for them to be open for the holidays is very nice and the staff was awesome. Melanie was very nice and made sure that my experience was great. The food was also really good. Overall, just a great experience read more

The food is your typical Denny's fare, cooked a little better than most Denny's. The big reason for five starts? There was only one cook and one waitress on a busy Monday evening. Annalily S was our waitress and you would never know she was taking care of about 30 customers at the same time. She was smiling and happy to help. She deserves a raise, she was amazing and cheerful. When leaving, my granddaughter asked me for four quarters for one of the claw machines. I didn't have it. Annalily overheard and handed her four quarters. (My wife paid her back). Thank you for such wonderful service. read more

I just wanted to do a review so I can say how fantastic Susan Was this morning she went above and beyond to help us! Also, I wanted to say how fantastic Liz is we have had her multiple times and she is awesome too! And the food is actually wonderful here and so are the decorations for every holiday! Thank you, Denny's for making our breakfast Wonderful read more

Susan was GREAT!!! I am definitely coming back again. From the moment we sat down Susan was friendly, professional and attentive. What a great experience for breakfast. I'll be back. read more

Nice time dining here in the morning, there was practically no one, sooo quiet. Breakfast burrito was good tho, my first time trying it and it didn't disappoint. read more

Dennys has been our go to lately for the burgers. The classic burger with fries is $8. You can't beat the price, and it's a very good burger. It's a good sized all beef patty. And it comes with wavy cut fries. Service is always good, the waiters are so nice and friendly and very attentive. They will check on you regularly and your drink never goes empty with them around. read more

I went to breakfast this past Monday with my family. The waiter by the bar section seems pretty serious, no smile or conversation. Sorry you had to work on Monday! Well I ordered the T-bone steak and eggs. I ordered it medium rare and it was made well done. I was pretty disappointed since the T-bone steak was thin like flap meat and over cooked. You would think since IHOP in San Dimas closed that Dennys would step up their game to gain more customers. With that said, I would rather drive the extra miles and go to the IHOP in La Verne from here on out. By the way, the red roasted potatoes were also over cooked and dry and they ran out of Fuze Raspberry Iced Tea! Not sure what's going on at this location. Maybe they were all hungover from Easter? read more

Melani, I just wanted to share this respectfully. You were kind and friendly, and I truly appreciate that. I did feel like the service felt a little rushed at times. When you walked away quickly, I didn't always get the chance to ask for what I needed. I also had to ask twice for ranch, my food literally got cold just waiting for it. I paid because I try not to be that person to ask her refund, but I had to eat my food cold. Yeah you were over there talking to the manager and doing other things this is what I mean by slowing down and taking time to listen to the customer I asked you for ranch, but you were so quick to walk away that you didn't probably even hear me I completely understand everyone has their own style, and customer service isn't easy. I just think slowing down a little and giving guests a small pause to speak could really make a difference. I'm sharing this with good intentions. Thank you again for serving me I wanted to friendly remind you I know you seem fairly young, but so many people wish that they had a job. Be grateful for the blessing that's in front of you. Take care of your job. I normally like to tip and I'm a good tipper as well however with the customer service that I received from you, you left no desire to want to do that. I hope that this helps you grow constructive criticism is good because it is how we learn sorry that I had to put this on, but I didn't feel comfortable having this conversation with your manager while you were present because I didn't wanna offend you again I wish I could have left a left no desire to do that. Everything was rushed either forgotten or ignored, and it was very transactional. I will not want this type of service again so when I come here, I would have to make sure that I'm intentional with who serves me unfortunately now because you did anything wrong I know that you might be learning, but I just don't wanna have to experience that again read more

So I have some beef with Denny's because every once in a while, I crave a plane waffle with whipped butter and syrup! However, the last three times I've been there I've gotten a waffle with bits of toffee in it. And it doesn't hit the same. When ordering this last time, I was very specific I want a plain waffle. The waitress said no problem. Guess what it had toffee bits inside so I was confused. after two bites I have to waitress over and I pointed to it and I said there's toffee in this she said is there really oh no I'll tell the cook and I asked her. Do you just have plain waffles with no toffee bits in it and she says oh no it's in the mix. So back up, I asked for a plain waffle she said yes they have it, but she knew it's in the mix. Just disappointed I feel like they could do better. Also, the bacon and sausage seems like it was made earlier that day. It was cold and nasty. And I spit it out in my napkin. When you're ready to go, I have to actually get up and look for our waitress. She was in the back washing dishes so I think that the cook and the server are the only two people there. Which is serve uneasy since we came at 8:45 PM. So I can see how they sort of cutting corners IHOP on arrow is very similar, I feel like the pizza and excitement is all sucked out of those restaurants. Not everything is made to order. (insert emoji sad face.) read more

Krystal was amazingly on our experience tonight! Food was great but her great attitude is very contagious read more

Food is 'ok' (Typical of Al Denny's), HOWEVER, ALL SIDES are an 'up charge', and are not identified as such on the menu. Plus they seemed very understaffed. I did feel sorry for the waitress, she was polite, but trapped by outdated ideas of 'what Good Customer Service' is. Further, she also acted as hostess & bus person. She said this is the chain policy on up-charges, not hers. We will probably cross Denny's off of our list for future visits. This was NOT a pleasant experience! Other Denny's I have been to did not have this problem! read more

Absolutely Horrible Hosting. Insane! Horrible attitude from the moment we entered - actually giving us very obvious dirty looks and making grotesque comments. Had the audacity to argue over something as simple as a menu item when we were literally pointing at how the item should have been made - continued to argue and then was making comments to the kitchen staff very loudly so everyone could hear. No offer of remaking anything just continued to say WE were wrong. read more

Walked in no hostess at front some person from kitchen yelled be right with you.watched the cook bring out food to a table,don't even see a waitress.we said this isn't good then we turned around and walked out read more

My husband and I look forward to having a meal at this restaurant and we always have a great experience especially when Liz Lopez is our waitress. The restaurant is clean; the food is always delicious and delivered promptly to our table. Liz Lopez is our favorite waitress, and we always look forward to having her as our server. She is very professional and pleasant in how she takes care of her customers. Her positive attitude and interaction with us as a waitress reflect on how she is passionate and loves her job. She is Truly an asset to your Denny's location in San Dimas, and we appreciate your excellent service. Lilly RP read more

Denny's is always good. The food is basic, good, flavorful, and plentiful servings. It's your 24 hour go to place.

I always go to Denny's at 820 S. Indian Hill Blvd., Claremont, CA for breakfast or just to get the senior grilled cheese and fries meal. It used to be on the senior meal, but it is no longer there. I wish it wasn't taking off. That was like my favorite thing to do. I think you all should bring it back. I was there at 10:29 AM on January 14, 2026 the waitress that took my order was very polite and made sure I had everything I had ordered. Her name is Cynthia Z. read more

Best service in the last year!! food was good also and the hit apple caramel dessert was amazingly delicious read more

Family Fun at Dennys after a great night of trick or treating. AnnaLily S. provided excellent service with a smile. She was attentive and kind. Her positive attitude made our time at Dennys very pleasant. Our food was hot and delicious we will definitely return to Dennys in San Dimas. read more

Absolute TRASH establishment. I was ordering in the app and something glitched sending my order here, I believe because I previously ordered at this one, but I travel for my work and now I'm down in San Diego. I called them and explained the situation. Not only were they rude, they continuously gave me the run around. I asked to speak to a manger and he was 3 TIMES ruder than the regular employees. I spent $30 PLUS a generous tip and I couldn't even be properly respected and treated with dignity. I am dealing with the loss of my teenage son and trying everything to still be kind and have respect for others, so to be treated this way makes it hard to keep my spirits up and positive. ALL. OF. YOU. Should be ashamed of yourselves. read more

BEST Dennys experience!!! I showed up at around 10PM on 8/28/25 and my party was the only table occupied. Less than 5 minutes after sitting down, one group after the other starts showing up until what seemed to be half the restaurant was full. Mind you, the only person working was Ms. Gail and the kitchen staff. My utmost respect to them. They had the efficiency and service of a full Sunday morning crew. The food was exactly as we had asked for it. Not once did I have to ask for a refill, I didn't see plates piling up waiting to be served, we were checked up on regularly and she kept a smile on at all times while being in a situation most people would have cracked. Above and beyond what I expected. Kudos to them. read more

The servers and the food was great. They get your order correct the first time. Zaman, Jose V, and Gayle are the greatest. It is better than the one I use to go to in Arcadia. I definitely recommend this Denny's. read more

Love Denny's Restaurant in San Dimas. Great service. For excellent service ask to be seated where Susan the server is working. Susan remembers our orders, what kind of bread we like & refills for coffee is is always there refilling our cups. We will only sit where Susan is waiting tables. read more

This has to be the best meal I've ever had. The chef was just amazingly so sweet to me and I got the original grand slam. The pancakes were cooked perfectly buttery and crispy. The eggs were so nice and fluffy and any times I've gone to any other Denny's eggs were not fluffy. Denny's is top-tier. I'm telling you no matter where you are in the LA area come to Denny's and they will get you right This is so beautiful read more

Krystal was amazing! Her service really brightened up my evening. The food was perfect post concert.

We always come in on Thursday nights after a long shift at work to see Krystal. She is hilarious. Always puts a smile on our faces. She is the most hardworking server I know. She can do it all! Cook, serve, and wash dishes. She definitely needs a raise.... read more

I would like to compliment one of your waitresses in your San Dimas location. Her name is Susan and I believe you can never have enough employees like Susan working for you. She is friendly, courteous, caring, hard working, attentive and conscientious. It is always a pleasure interacting with her and she has a genuine interest in your well being. People like her are few and far between and she is definitely a valuable asset not only to that location but to the Denny's franchise as a whole. read more

This is in regards to Dennys in San Dimas: We go to Dennys every weekend (Sat and Sun) and we enjoy all the servers but "Susan" goes way beyond.
