July 29 · Karen HurleyI had such a great experience at Denny’s thanks to our server, Kayla. From the moment we walked in, she greeted us with a warm smile and a kind attitude that immediately made us feel comfortable and welcome. She was incredibly attentive the entire time—checking in just the right amount without being overbearing, and making sure our drinks were always full and our food was exactly how we wanted it.
July 04 · Ricky RWell sadly this location used to be favorite however the food was just ok. I thought ordering the sampler would be the safest. I was wrong, my wings looked and tasted like they just tossed old cold wings back into the fryer and didn't even bother to put adequate sauce on them to at least pretend like they were new. I'm very disappointed. I was looking forward to coming to this location. In hindsight I should have waited until I got back home and Payson to eat at Denny's and get my sampler.. I guess I could have been more understanding if they were busy however there was only on other family in the entire restaurant.
October 04 · Ashlee FordWe had a seriously great experience! I’ve had some pretty disappointing visits at other Denny’s spots in AZ, but this location totally changed my mind 🙌The place was clean and had a chill, welcoming vibe 😊 Our server, Cheryl, was awesome—super kind, patient, and on top of everything. Drinks and food came out fast, and she was just really thoughtful the whole time 💯As for the food—props to the chef, Ralphie 👨🍳 Everything came out hot, well-seasoned, and plated like someone who really takes pride in their work. It looked good and tasted even better!We’ll definitely be back. This Denny’s got it right ✅😁
