So, I've never had authentic Nathan's and, based on reviews, wish I'd had the opportunity to try it before this Vegas excursion. But if you just want a chili cheese fry and a hot dog with relish, ketchup, mustard and onions, Nathan's at MGM is sufficient. The food was fast food good. But they did mess up the order which should have added chili and cheese to the dogs. Mind you, I'm a burger and fry freak who does triathlons at the Iron distance so I don't take my cheat meals lightly. And I was more than happy to gobble down this hot mess before moving on to the next adventure.
