The Ultimate Las Vegas Bar Experience—Customized by You. In a city known for its nightlife, Sip Happens brings the elite lounge experience directly to your doorstep. We’ve reimagined mobile bartending by combining premium mixology with a smart "Dry Hire" model. How it Works: Your Event. Your Alcohol. Our Expertise. Standard catering companies charge a massive markup on spirits. At Sip Happens, you provide the alcohol, and we handle everything else. This gives you total control over your budget and allows you to serve the premium brands you actually love—without the "Strip" prices.
