Decent Lounge area. Went to Vegas for New Years and was still around on Monday. Free seating made this a great place to just chill out and watch the crowd. There were some BCS games on and the people walking back and forth served for great entertainment.
Heatlamps did there job too since this time of the year is quite chilly.
The drinks are pricey, $40 dollar pitchers which come out to about 4 cup fulls do their job. If we had to pay a cover then Rhumbar would easily lose a star. The waitress pours your drinks for you so you feel that your tipping is well deserved--but to be frank and honest, I rather pour myself and save the money for more booze.
The decor at the bar is great, large glass doors and white scenery really makes it feel classy. Like anything in Vegas, the crowd has a lot to do w/ everything, on a day like the day I went, the crowd was ultra chill. I feel like I'm getting old... I'm more likely to give a buffet a 5 star rating than I am a lounge, HAHA, sad....
