From the moment I walked in, I was greeted with genuine warmth by Armando and Dina, instantly setting a welcoming tone. The service was excellent — Fernando was attentive without ever hovering, keeping my coffee topped off and making sure I had everything I needed. His friendliness and professionalism made the experience feel personal and inviting. I ordered the French Toast Slam, and it was delicious. The French toast was golden, fluffy, and perfectly sweet, paired with fresh eggs and savory sausage that made for a hearty, satisfying meal. Everything tasted well-prepared and far better than what you might expect from typical diner fare. The restaurant itself was spotless, with clean tables and an inviting atmosphere that made it easy to relax and enjoy my food. Overall, this Denny’s stands out for its warm service, quality comfort food, and clean environment. If you’re in Placentia and craving a great meal in a friendly setting, this location is definitely worth a visit!

Amazing experience at Denny’s! Fernando gave us friendly and prompt service, and manager Dina made sure everything was perfect. The Fish and Chips were delicious and the Country Fried Steak was hearty and tasty. Great food and even better service!

Stopped by Denny’s recently and had a great experience! The place was clean, cozy, and had that welcoming, family-style vibe. Everything was well-managed under the care of Armando, who keeps things running smoothly, friendly, and professional touch. The menu has so many options from breakfast plates to lunch and dinner favorites. Everything came out hot and fresh, and the portions were generous too. Definitely a solid spot whether you’re in the mood for pancakes, burgers, or just a good cup of coffee. A great go-to place for comfort food and a relaxed atmosphere. Will be back!

We had an amazing breakfast experience here and couldn’t be happier with the food, service, and overall vibe. From the moment we walked in, I was greeted with friendly smiles and seated quickly. The place was bustling but well-organized, and our server was both attentive and kind! Highly recommend this spot for anyone looking for a solid breakfast, whether you’re visiting or local. I’ll definitely be back with my family for breakfast!

I arrived at 11:00 am. The servers and manager were extremely kind and helpful. I was immediately seated. I ordered breakfast. My coffee cup was never empty or cold. I had pancakes, eggs and sausage and it all tasted delicious. This breakfast was my second time there in the past two weeks. The first one was also delicious and with perfect service. I was there at 5 am, the first time. There were 3 customers there. It was great! We were leaving at 6 am and it was a good thing because the breakfast rush was starting. I went out of my way to go back so I could have their delicious pancakes again. 🥞 The atmosphere feels kind of cozy to me. The restaurant was clean and had a nice style. The restroom was also clean. I recommend this restaurant especially if you want friendly service and delicious pancakes.😊

Joaquin is hands down one of the best servers I’ve ever had. From the moment we walked in, he was friendly, attentive, and genuinely welcoming. He had great energy, made sure our food was perfect, and checked in just the right amount — not too much, not too little. You can tell he actually cares about giving people a good experience, and that made all the difference. Also it was like 3am

Foods were delicious. Dina always greets me with a welcome voice. She also remembered my usual order. The restaurant is always clean and always my first choice to go.

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

This is a great Denny's. Its tucked back off the road a little bit with the Best Western just behind it but you can't miss it if your looking for it. It's a bright and clean place and the layout gives you enough separation so you don't feel like other dinner's are sharing your table. Denny's food is always good and the service was here was best I've had in a long time. Over all everything was really good.

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.

I was disappointed in this particular Denny’s. Well to start, the staff really didn’t seem that friendly, especially when I told the waitress that we just came for dessert. I guess she was expecting a big dinner/ big tip. But what got me, once we got our dessert. They looked bad. I mean my cheesecake was covered in strawberry sauce, with no strawberries, and the whipped topping barely made it onto the cheesecake. Our Apple Pie Crisp was more crust than apples and it also looked ugly. I will admit that I was at least happy that she served us fast, and at asked for a refill of our coffee. But this is the few times I’ve been to a Denny’s and did not feel welcomed. On the plus side, very few people seem to come here, so it was empty compared to other establishments. We just needed better customer service.

Food 👎 Service 💯 The fish and chips and country fried steak are just extremely greasy to the point they are just yucky 😝. The bacon 🥓had absolutely no flavor. Worst of all there's no assistant manager/manager on duty in the evenings so no one to complain to 👎😡
