Roy's is our favorite restaurant in Las Vegas. Sometimes I get their Prix Fixe menu which costs less than $40 and includes 3 courses from a limited menu. We always get the chocolate lava cake. It's the best, but order it early as it takes about 20 minutes to prepare.
We go to Roy's to celebrate special occasions. They will usually ask you if you're celebrating anything special when you arrive. If they know that you are, they make the night special by giving you a framed photo of your group along with a chef's choice dessert.
Just a heads' up. We tried their happy hour once and the food specials were incredibly small. The sliders were about the diameter of a quarter. Why bother? LOL.
Stil our favorite place, the menu is always changing, the food is great and the service is very personalized.
