I’m sure there are plenty of all night diners in Las Vegas. I’d bet you might even be able to find a few that blow Denny’s away in regards to food and price. This Denny’s is located somewhere on the Las Vegas Strip. The neighborhood might be less than tourist friendly. Once you pass the Encore hotel and casino you will come upon The Gold Key Shops. There may be another shopping center located in this area as well. I honestly can’t remember which strip mall this Denny’s was located in. All I know is you will come across it by the Encore on the way to the Riviera casino.
