Getting to this sleek, stylish lounge is half the fun. You have to take a glass elevator 64 floors up and then you'll be greeted by the curved bar and high, scarlet light fixture of MIX, companion to the adjacent French restaurant of the same name. Huge windows entertain breathtaking views of the Strip, and if you have no fear you can venture out on to the patio, where intimate tables and even beds await. For the VIPs, a stairway leads to a private, hidden area located above the larger main bar. Mix serves a light food menu until 11 p.m., and drinks average $10-$12. If you're looking for a more substantial meal, the lounge is located adjacent to Mix restaurant.
