Ordered over medium eggs and was served over hard eggs. My wife ordered over easy eggs and was served over medium eggs. My coffee cup stayed empty after I was served My first cup. My wife ordered biscuits and gravy and the biscuits were so hard she couldn't cut them with a knife,and the gravy was cold. The hash browns were not crispy on top and tasted like they were made from dehydrated potatoes that were not dehydrated properly.

The food was really good. The salad I had was fresh and looked very appealing. My husband's order was hot. The waitress, Jessica, offered salsa as a side for his meal and asked if I had enough dressing for my salad. Drinks were promptly brought and refilled. The place looked clean and organized.

As someone who frequently visits this location, mainly for breakfast, always get great service. Especially when Abby is working. I wish this location was available for more hours.

We just love our hometown dennys! Our family visits every Sunday after church and we always request Abby. She is attentive, always a familiar smiling face, and someone we look forward to seeing every week! Everyone is wonderful here! Quality food and staff!

Everything was great this morning. Me and my four children came for breakfast. I only subtracted one star because the bathrooms were soo cold I didn’t want to pee anymore, I can’t even imagine how cold the toilet seat would be. Brrrrr…. Food and service was exceptional tho..
