The Mandarin Bar is actually my go to lounge in Las Vegas. I mean this place is absolutely world class and legit in nearly all facets of the business. There really isn't words to describe the beauty and sophistication associated with this establishment nor the level of service provided. From the moment you walk in, you know you're in for a treat as the ambiance is wonderful and there are views for days. Drinks can be a bit pricey but worth every penny if you ask me. Be sure to make reservations in order to get a seat near the window. Overall, very highly recommended to those looking for a great night out, on a date and/or entertaining guests.
