Great food. Everyone enjoyed their food. A little disappointed with the boneless wings amount. I received 8 for $13.

Great service and atmosphere. Employees ate great. Just went yesterday. Food was on point. Only issue is parking is tight. Make sure you park on north side of building where there is more room. The south side is closer to the door but parking is limited. They still have budget menu under 10$ an entree.

Had breakfast here around 8AM~9AM on a Friday. Server was highly attentive and fluently bilingual. There was a minor problem with our order that he had noted and addressed right away. Very satisfied with the service. Place was rather busy and packed, but still comfortable and relaxing enough to enjoy breakfast. Update: went again and got the bourbon chicken skillet. Amazing, just what I was looking for after work, which is breakfast for others, but dinner for me. Happy they serve more than breakfast! Service was good like last time.

Hi, we are finding that Denny’s has upgrades their food and service. We usually focus on the senior menu on the back page of the menu, but everything we have tried is fresh and well presented. We also like new lights ( see picture).

Denny’s is always a reliable spot for a good, hearty meal. The menu has plenty of choices for breakfast, lunch, and dinner, and the food came out hot and fresh. Our server was polite and attentive, checking on us just enough without hovering. The restaurant was clean and comfortable, though it did take a bit longer than expected to get our food. Overall, it was a pleasant experience — good food, friendly service, and fair prices. I’d definitely come back.
