Located on the first floor of the Cosmopolitan near the main lobby, Vesper bar is one of the best in Las Vegas.
Vesper specializes in retro cocktails with a modern twist. This is not a bar to order Bud light at, you'd be missing out. The bartenders are friendly and prompt, they are also a wealth of alcoholic concoction knowledge. Vesper has one the most impressive collections of alcohol I have ever seen.
Vesper is a upscale and higher end bar. With speciality cocktails ruining around $14. There is plenty of seating at the bar as well as a large area behind the bar with semiprivate and intimate booths.
Vesper get very busy on weekends with lots of traffic coming in off the strip and out of Marquee nightclub.
Overall and excellent bar that will keeping you coming back for the drinks and atmosphere.
