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

Service was great, our server Susan was very attentive and had a great attitude! This is our neighborhood Denny's so we will be back!

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

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

the waitress was very sweet! the food was amazing and very well done! 10/10, i love the ketchup here its amazin, it always smells so amazing in here aswell, the bathroom are always clean! yay read more

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

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 I did feel sorry for the waitress, she was polite, but trapped by outdated ideas of 'what Good Customer Service' is.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.

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

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

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

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

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

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

Went for my birthday. The food was great and the waitress was amazing! They were able to fulfill all of my requests. We asked for a booth away from other patrons, and they were happy to meet our accommodations. I told the waitress that I hadn't had a chance to explore the San Dimas area much yet, and she gave me some great recommendations for local entertainment and I had a blast for my birthday! Definitely will be back! read more

AnnaLily is a great server and very helpful whenever you need anything to ask on especially for another order too! 10/10

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

Had business in the area, and this is the one place that is open late. Typical Denny's, nothing special, but you can depend on it for freshly cooked food, hot, reasonably priced. The service was pleasant, but can be slow. Can't beat it late at night if you're hungry.... 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 an excellent Denny's. The food came quickly, the waitress was authentically kind, and it was clean inside. All around an extremely pleasant experience. I was here at midnight, results may vary. 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. She makes our experience at Dennys extremely enjoyable. Thank you for hiring the quality of personnel that you do. In allowing Susan to put up with our antics. She's a gem. We give her 12 out of 10 Stars Thank you, Michael and Frances Miranda read more

Me and my girlfriend come here almost very often. We sometimes go each day of the week. The place is clean, food is made good. And over all it's very easy going. I love the 2 lady employees there because they're the nicest workers and excellent at customer service. My only problem with the place and service is the Elder Woman that's works there some days. She is very rude and makes backhanding looks. The way that it seems, she doesn't like young folks very much to my guess., she deliberately makes us wait long to order, charged us extra one time and I've noticed it, and once I brought it up she tried switching her character. The other day we had went in to order to go, and she had us waiting while she got to every other customer (who were mostly elders as well) and even got to the ones that were there after us. We noticed it and decided to just leave and eat else where.. she has acknowledged the things she's done but still occasionally continues. This place is good but it could be better without her in my opinion. I see that she acts like that with other younger folks so it must be a personal thing. From now on I only go here if she isn't here. And if she is. I guess I will be taking my appetite elsewhere where read more

Sweet waitress and good service. perfect time to go and eat with friends. Food was tasty, we got it fast. Thank you to our amazing waitress krystal . read more

Krystal P was great! Great service & really funny too! The food was great and the facilities were clean :)

Dennys is often underrated as a coffee shop but their dinners sandwiches and nachos are the best. I only order nachos with guest because the serving is so big! Dennys San Dimas and Dennys Covina are our favorite place to meet friends! Delicious as usual. Today we are ordering from the seniors menu just enough read more

Today was such a great experience! Food was hot and fresh and so delicious! 10/10 on the Service from Susan and Ana!!! They really go above and beyond! read more

Food was good.I just wish our waitress checked up on us and asked us if we needed anything.Susan was just a little slow this time

Worst Dennys restaurant hands down. My Granddaughter took me to breakfast, wasn't full or really busy. Food took forever and when it did come, the hash browns were raw, when the manager did his rounds when we where almost done, I let him know, all he wanted to do was make me a new one, at that point we were already done, and didn't want to wait any longer the we already had to. Offer nothing to discount the horrible breakfast. Won't ever go back. Done with Dennys in La Verne. read more

Before I start saying anything bout the food and the service. I want to start off by saying I am the black woman that was seated at table #47 with the black hair and grey sweater with tan shorts and boots on. My waitress gave bad service he gave me my food n quickly ran off without asking if I wanted anything else also I did not like my strawberry stuffed french toast. I made sure to tell her that n ask for something else and she quickly responded by saying "well what do you want " with out giving me the menu again to try to figure it out. I ordered chicken fingers instead and I asked for ranch and bbq sauce but she never gave me the ranch n quickly walked off without asking if I'm doing ok just like she did to everybody else. The chicken fingers were way too salty so I decided to go home without finishing all of them. I forgot my waitress name but she had white grey hair and she was an old woman. I walked into the restaurant at 10am and left around bout 10:30am - Posted Review: Saturday January 13, 2024 11:04am read more
