Had an extremely late early am meal with some friends celebrating our endorsement for our elections. When entering we were offered to sit anywhere in the section off to the right. We chose to sit in a booth. The waiter and waitress that assisted us were both friendly and helpful. I love when they take orders and memorize them. It shows the dedication to the job, especially when it's correct. I opted for the Cali Club Sandwich. It's has roasted turkey breast, ham, applewood bacon, Swiss cheese, avocado, lettuce, and tomato. I got no mayo on mine. I also substituted fries for onion rings. The sandwich was light and well balanced. The avocado makes it perfect. The onion rings were crispy and not too greasy.I just wish it had a thicker slice of onion because it was more batter than onion. The ambiance gives 50s diner. They offer booth, table, and counter seating. The nice thing about Dennys is it's opened all night. I'm not a huge fan but I was pleasantly surprised how much I enjoyed this sandwich. read more

Juan the server is beyond amazing. Great service with a smile and personality. Not only did Juan treat his customers with excellent service he also was very respectful. The man is such an amazing asset to Denny's. He was non stop. When he wasn't waiting on tables he was cleaning getting things in order. He was non stop. Such an asset to Dennys. I pray he will get recognized for his wonderful contributions to Denny's as well as his excellent service to his customers. read more

I ordered delivery of a breakfast. it sat for almost an hour before pickup and they still gave delivery driver a cold meal to deliver. it was not edible. there was cold coffee , warm orange juice, cold eggs and hard cold waffle. I called the Denny's in question and they blamed it all on delivery service. What restaurant would send out a cold meal and blame someone else for it. read more

We had gone to take family out and Vivianna did a great job on taking out our order however the kitchen kept making it wrong after 3 times we did not want it anymore. They took it off our check which makes sense as we didn't get to enjoy it. Then the manager did not help and did not offer anything to make the experience better. Poor service from the manager. They need to better their hiring when it comes to someone making better decisions: read more

So, came back with my friends because this place is the only place that provides decent service at 2am near us with good food. Montana took care of our table! She was just amazing. She provided us amazing service. The crepes looked literally amazing, BUT unfortunately was not really edible, crepe was really dry and part thin, it was like eating cardboard, Montana took the plate back no questions asked. Love the Oreo shakes here and their burger I got was delicious :) definitely made up for the inedible crepe! Fast service and really attentive staff :) read more

We came here for breakfast after a doctors appointment across the street. First, the energy you feel when you walk in is infectious. Angel greets everyone in a friendly and welcoming tone. We were sat right away. Cupertino H was our server and I have to say, he is friendly and fast! He took our order as soon as we were ready and he pays attention to everyone. You don't have to look for him, he already knows you need a refill without asking. The food was so delicious! I got the eggs and chorizo with jalapeño and I will definitely come back for it. My husband had a bacon avocado cheeseburger and said it tasted to much better than other burgers at gourmet places. If you haven't come to this location yet, you need to. They proved customer service is still alive and kicking and we had a great experience start to finish. Thank you Cupertino and Angel! read more

I want to express my concern: I visited your restaurant, which is advertised as open 24/7, but upon arrival, it was closed. This is not the first time this has happened. On several occasions, I have passed by and found the place closed, while seeing an employee outside smoking with two other guys. This creates a very poor image and causes distrust. If the restaurant is advertised as open 24 hours, why is it closed? I hope this issue is addressed promptly. read more

Jessica was an amazing server. Treated me and my family well. She was very attentive and asked all the time if we were going okay
