My brother and I have been going to this Denny's for over six years now. We usually go after 10pm and on Thursdays - Mondays only, because of one man, Ron. Ron is by far the best food server in Las Vegas, and I do mean the best food server of any restaurant I have been to, in arguably the food capital of the world. He is very attentive, responsive, and most importantly caring and kind. Most of the time he is the only front of the house employee, and yet no matter how busy they get, he never loses his composure. He is the greatest, and deserves a ton of credit for his work.
A:
4 stars
