I have never had such bad service in my entire lifethe Denny's in Pleasanton is the worst ever I've seen people walk out of there it's just a horrible place management needs to go to the store immediately and talk to the entire staff I have no rating

Madisonville Ky wins the worst Denny's resturant across America. Slowest service, worst food and managers. 2 hours at Denny's and still brought a bloody steak, I ordered well done. This was their second chance! No more. Cracker Barrel and Applebees will get my business when visiting here.

Are you talking about the Pleasant Hill Denny's or Pleasanton? The Denny's in Pleasant Hill, I am surprised it is still there. It has had problems before.
