Our waiter/server ARMANDO was attentive, quick, polite and very pleasant. We came to eat here on Sunday October 12th 2025. I just wanted to share that these days you don't really get good service anywhere anymore, so when we do we wanted to acknowledge it. Thank you Armando!! Also the food was good and the inside looked very clean and pleasant.

Arrived around 7:30 am, no line, was seated right away. The waitress got to me immediately and was very attentive and polite. Good arrived 15 min later, hot and delicious! I had the quesadilla with bacon and scrambled eggs. Fluffy and fresh! The place filled up pretty quickly and can got pretty loud. Very close to Knott's Berry Farm and Hotels in the area.

We had perfect service at this Dennys location. We had a friend with us who had mobility issues, and the server noticed that and gave us a very nice table which was easy to sit at. Then very attentive. Dennys has some really good value meals.

I went to this place to talk with my client last night, it was a good experience, especially people who worked were kind. A worker, his name was Manny, he was very kind and helpful when I got trouble to pick up my earphone ( I dropped my earphone accidently and couldnt reach to it ) even after we had paid the tips already to another waitress. He was not the server of my table. Nowadays I was thinking servers show kindness only when they are expecting tips, but I guess I was wrong. I will go back to this place again. It was quiet and clean too.

We had a great dinner here tonight. excellent preparation of a sirloin for wifey and great chicken fried steaks for me. I have had the pot roast elsewhere would recommend it. I noticed the spaghetti dinner was not on the menu. They have 24 hours again, breakfast all day as well. Location is handy to a few places we go. will remember it's there

OK man after a long shift, thought I was gonna be half to ready for Some bad experience proven otherwise by the exceptional most out of the ordinary service that the host attended me with took my order. Talk to me like if I was a decent human being as well, which is rare to see nowadays I just want to say Denny’s is still holding it up holding it down being the best they can be and this store here is the representation of pride over years

Visit the restaurant today. It was packed but the staff was professionally took care of me. Even though there were a ton of people, they managed to get the order out quickly. Food was hot and tasty. The store was clean and full of the holiday decoration. I really enjoyed my Christmas there. Will be back again.
