elivria was a great host and very hospital helping us as a group of over 15 people and on mu occasions

First time coming to this Denny's location with my family since it was nearby to us. We were first greeted at the door and seated immediately in a booth. Each of us individually had the rewards app as we get a reward for a free original grand slam meal, each of us do. We ordered our food and waited. The meal items come on 2 separate plates. The eggs, bacon, and sausage come separate from the pancakes. Our server brought our plate of eggs, bacon, and sausage first. We waited quite a bit for the pancakes. By the time it came, we had eaten all of our other food. Server should have brought everything out at the same time and not separately. We also were given the wrong check to pay. The place was not busy. How do u make a mistake like that? As we went up to pay, we mentioned to our server whom also handled us paying about us having rewards and free original grand slam meals which we all ordered. She told us to next time let her know from the beginning cause now she would have to make 3 separate checks. We had no idea and nothing was stated in the terms and conditions that we had to do that. The 3 stars unfortunately was due to our customer service. We did tip our server cause the meals where all free and we didn't order anything else, not even drinks. We most likely won't be coming back to this Denny's location though due to the experience we had. read more

What could improve? A lot actually. Lol, ordered breakfast for the family and I. Ordered the rudolph slam, it came with no eyes or nose, mom had gotten the new chorizo scrambler that came with toast, no toast. Ordered my kid a mini pancake slam and the pancakes are burnt. As well as my mom being ignored waiting for her food. Worst Denny's experience. No wonder they're considered underperforming. Gonna head back and see if they give us a fair refund. read more

Server not too friendly : no smile looks like she was so tired and overworked since we came around 11 pm. She was the only server on that shift and it was quite a busy nite with i think 5 -6 tables she had to serve. Had to flag her down for service . Left the check turned about so quickly , didn't say a word and didn't ask if we needed a to go box for the leftover which was my half sandwich, really??? Ordered the pot roast melt and so yummy !!! 3 stars for the food !!! read more

Service was not up to standards.Overpriced meals for mediocre food. You'll get better service going to a fast food chain. This was my experience at the Ontario location, off of Milliken near the 10 fwy. read more

Folks are very friendly and it was 130 in the morning. A large party was served with very good looking food. Another party of 8 was waiting to get seated. I sat for 30 minutes and left because it was clear the one cook was only cooking one ticket at a time. They also served a guy next to me that sat 10 minutes after we sat, but got his food. We went to ihop and got our food in 9 minutes. That's what Dennys is suppose to do. But you should go to ihop. read more

Immediately upon entering this gentleman greeted us he was in a upbeat mood. Loved that ! Adriana was very attentive she made sure we were taken care of. I loved the fact that they have a senior menu for my mother in law. Not many places offer senior plates. Our burgers were out of this world, so fresh, seasoned well, not trying to throw anyone under the bus but a 3 patty burger wow I don't know what a big mac is ! read more

The service was horrible! I tried placing a phone order and spoke with Juanita and she told me I couldn't replace red skinned potatoes for hashbrown I told her I do online orders all the time at other locations and she said to do it online since she can't help me so I did and when I got my order they did not satisfy my request and it's a disappointment because it was my first and definitely LAST time coming to this dennys! So rude. Do better JUANita read more

He is not eating the food I am. And if I don't like my food sorry sr you need to sucked up. Cost I am paying for your service bad experience over all Damian you need to be fired my man time to retired bad attitude read more

The first Denny's who do not serve plant based options ! What? No healthier options. It's no wonder people have high cholesterol! This location can also be a little cleaner especially at the entrance ! I almost left but since this was a Denny's location on our drive out to Pasadena, CA we decided to try it out. Last time ever! Surprised this is even an A rating Dennys! read more

I usually don't write reviews, but since I had such an amazing experience today, I had to do it. As soon as my cousin and I stepped into the restaurant, we were both acknowledged and greeted by a very nice gentleman named Ruben. Ruben was also our server. He was very helpful and polite. He made our visit such a pleasant moment. Our food was just on point and so delicious. The restaurant was nicely kept clean. I highly recommend this location. I will be returning back to this Denny's very soon. I'm making it my to go Denny's. read more

Place clean. Ok welcome service ok but can be better. Only one person serving about seven plus tables. Never came back to our table and ask what more do we need. We had to wave and get her attention when we need anything (even just water refill or more napkins) Patty melt was good. Salad not so ok. Veggies didn't seem fresh (brown edges in some lettuce), chicken on the burnt and salty side. Not a very good late nite dining experience but will probably give it another try. read more

Tonight we came to Dennys after the movies and we had one of the nicest servers Tia, she was absolutely amazing made sure to give us some options on the menus they have, our food came out super fast and she made sure we were well taken care of. We should have more servers as nice and attentive as her. Love Dennys and their pancakes:) read more

Jisselle's service was A+. And even came outside to give me the water bottle I forgot at the table!

Dined at this location and was very pleased with the service. My server was Ruben and he was very knowledgeable with all the food items on the menu. He was very attentive and professional, I like how he kept refilling my coffee mug without me having to ask. Also the restrooms were clean, will definitely be back. read more

Tia was amazing! Thank you for your attentive and friendly service. We would happily return to this Denny's when in the area! Thank you! read more

Went to grab some food with friends and we had Tia as our server. She was so sweet and attentive. The banana cream pancakes HIT ‍

I have came for the last two nights in a row. My waitress Tia was amazing and remembered me right away the second night I came in. She was super sweet and helpful, my food was fantastic especially for being so late at night. It's hard to find a good place that is quiet and being able to eat in peace while doing some work on my phone. A definite go to if you are staying at one of the local hotels or in the area in general. read more

The times when my family and I have gone into Dennys Tia gives you this happy greetings. She makes you feel like you are at home serving us your amazing meals. She is the best and most friendly person and makes you want to keep coming back. read more

First time coming here and we got seated right next to bathrooms. Ugg we could smell the odor so we asked to be sat somewhere else. Finally got down and ordered triple slam breakfast. Overall food was good. Pancakes were a little burnt but still tasted good. read more

The service was great considering it was not busy. The food was great! My boyfriend and I went to this location and the ambiance was not great, the 3 women there were talking loud about their business in which we didn't have to hear about it. One of the women were talking to one of the cooks saying that a woman being separated but then a man was trying to steal her away from the cook that she was speaking to, I don't think that was very appropriate. One of the servers was saying that she was dating a man that was already in a relationship with another woman, I don't think that was something we needed to hear. My boyfriend and I felt uncomfortable and we had to finish our meal quickly. I am not saying that they cannot talk to each but please keep it at an inside voice level where the guests including my boyfriend and I have to hear it. Other than that I enjoyed the service and the food. read more

Conveniently located right off the 10 fwy off Milliken Ave exit with plenty of parking. We stopped on a busy Saturday night & were seated immediately. Fast, friendly and efficient service. Shout out to our server Larisha who was extremely attentive and helpful with the menu, she was very organized and made sure we were well taken care of. We ordered their 'Bourbon Sirloin Dinner' & 'Chicken Fried Chicken', both tasted delicious with that authentic Denny's taste and were cooked to perfection. The restaurant and restrooms were clean. Overall, we had an excellent experience at this Denny's. read more
