Description

At Denny's, guest experiences have been notably mixed, highlighting challenges in service consistency and food availability. While a few patrons praise the food quality and exceptional service, particularly from staff like Kurstyn and Hunter, many others report long waits and incorrect billing issues. Instances of overcharging and miscommunication have left some diners frustrated, with several vowing never to return. Despite these concerns, the restaurant’s ambiance received positive mentions, especially in newly renovated locations that offer a welcoming atmosphere. Overall, while Denny’s has potential, it clearly requires improved staff training and management to enhance customer satisfaction.

This Denny's location is terrible! The staff needs proper training, teamwork, and leadership. The server never came back after delivering the food, and there was no manager or lead in sight. The food arrived slowly and was served lukewarm, with some items missing. There were no beverage refills either. It's clear that poor management is to blame for this experience!

We had a new server who really messed up our bill. We were way overcharged because we were billed for the wrong things. Not the waitress fault, she tried but they need to start making sure everyone is properly trained before sending them out on there own.

Just spent over an hour waiting on food we never got. We literally saw our server twice. Once when she took our food/drink order, then we she brought the drinks. Never saw her again. Then the hostess actually charged us $6 for our drinks! Tell me you don’t care about customer service without telling me. We’ll never attempt to eat here again. Yet another restaurant in a truck stop that doesn’t care about the truckers who move America! Way to go Dennys! Food: 1 Service: 1 Atmosphere: 1

Reset at Applebee's almost an hour never was offered a drink or anything then the manager was coming out we thought he was coming to talk to us about a delay or something but he came to a table that was sitting next to us cuz the lady said her steak was raw and see why I didn't well done and he told her that it was done for her what does she wanted **** still alive on the plate and she tried to argue that she wanted it well done and he said no you didn't so we just stood up and automatically left I don't think that was proper and then we ended up at Denny's in Missouri where we walked in and the mood was set right everybody was smiling nice everybody's eating had something to drink we were welcome by kurstyn with the big beautiful smile got to start drinks as soon as we walked in our food was perfect we got it fast I would recommend this place to anybody that started I wasn't sure what to expect after eating at Applebee's Food: 5 Service: 5 Atmosphere: 4
