Review for The Cosmopolitan of Las Vegas Review For Holsteins Google User May 17 '18 at 2:18 I've been here the last 3 times I've been to Vegas, and I've got to say, the Billionaire Burger gets better every time I have it. We originally went here because the line for eggslut was too long, but it was a good thing we did because now this is a must go whenever I get the chance. Friendly staff, good food and drinks, and short waits make this an awesome choice. View full site to comment or like
