This has to be the worst Denny's in Nevada. It claims to be 24 hrs however should you get hungry in the wee hours plan for a long wait to be served, poor customer service and horrible level of cleanliness. As we pulled around 2am to eat the waiter apparently had an errand to run despite the fact that we were walking in. We sat for 15 minutes in a desolate restaurant calling out to anyone for service with no response. There was an employee in the restaurant dressed in Black I assume to be the cook and despite our calls for recognition even he refused to respond and stayed in the back. Another group of customers arrived and waited the same. While there I took the opportunity to share photos of what the tables looked like at 2am with no one in the restaurant. It's obvious that the employees could care less about cleanliness or service. We decided to leave and spend our money across the street at IHOP which is also 24hrs. The service was great, the food was fresh and the restaurant was clean. It's been years since I stepped foot into a Denny's and I will Never again thanks to this horrific experience. Don't waste your time or your money!
