    I wish our Denny would be more consistent and they need to remodel our restraunt it's very dirty and the staff is very rude it's a shame because it could be a great family restraunt.

    I got the all you can eat pancakes. I had to ask for another plate. They say you get three then two from that point. I got two then asked for two. Called it a day. I hated to ask. I won't return.

    Hi Leslie, thanks for the feedback. Hope to see you again soon.

    We have found that 99% of the time we go to this restaurant that the service and food have been better than average. The staff always gives us the feeling that they appreciate our visit. Food us prepared as expected and the service is above average the times we have been in the restaurant. 100% of the time you visit a restaurant, you know what type of place it is based on the condition of the restrooms. This also gives you a representation of the cleanliness of the staff and the "back" areas including the prep and kitchen areas. The restrooms in this Denny's have usually been clean as well as the public dinning area. Staff has always been clean and professional.
    Our visits have been pleasant and relaxed every time we have gone in this Denny's.
    Denny's is welcome to use my comments.
