I LOVE THIS PLACE!!!! Growing up in SoCal, I used to visit Ruby's regularly with friends and family. Since moving in Las Vegas, sadly I can no longer get my Ruby burger fix unless I am flying through D gate at McCarran Airport.
As a few fellow yelpers have stated earlier, when it comes to Sunday (or any day for that matter) hang over food, nothing beats a Ruby's breakfast sandwich. Heck.... get the chili cheese fries to because they are epic!
Granted there is only one drawback to this little dinette.... the price. But then again.... ladies and gentleman of the traveling public, it's an airport, your a captured audience, so prepared to spend a little more then you should for that meal, it's just the way it's got to be.
But seriously though, this place has the best burgers in D gate, if not the whole airport! :)
