I took a walk around the development last night and came across the Mandarin Bar on the 23rd floor of the self named luxury hotel.
This hip and modern lounge is surrounded on three sides by glass and offers "fan"tastic (pun intended) views of the strip.
"A double height wall of liquor bottles is spectacularly backlit by the glittering Las Vegas Skyline. The interior offers a contrasting dark intimate mood with billowing fabric pane,s shimmering in the light. Discreet seating arrangements give guests privacy and comfort. Our bartenders are master mixologists and will create cocktails according to the flavor and sensation you are looking for."
Being new, I need to cut them a bit of slack in regards to the level of service and drinks delivered. In regards to the ambiance, definitely worth the visit.
For other view worthy stops in the Sin City - visit Moon, Ghostbar, Mix or e-mail for more suggestions.
Cheers!
