Awesome place to hang outside, enjoy a cocktail and a smoke, and listen to some tunes. The guy that serves the hookahs is really cool, too. The wicker sofas are pretty comfy, and their signature mojita is an excellent cocktail, as is their latin manhattan, and pina colada. I wouldn't recommend the inside portion, as it doesn't even feel like a bar ... It is bright, narrow and looks more like a sushi bar, than a cocktail lounge.
When the weather is nice, the patio at Rhumbar is one of my favorite places to chill and people watch on the Strip. AAA+++
