It's unfortunate that this review needs to be so negative however despite good food and great portions our experience at the Diner was ruined by the rudeness and inappropriate behavior of the young lady who is managing it. Upon receiving our bill, we provided a gift card we had received and it was refused. The manager had the waitress tell us they have a new system and cannot access the values of any "old" cards therefore they are not accepting them. When questioned as to how that is possible when the card is less than a year old, she didn't move from her position in a booth in the back, just restated that it's too old and dismissed us. Her attitude and complete disregard for customer service will result in our never going back.
