Worst club/ lounge on the strip! Don't go!!! Bartenders suck! They r too busy trying to get ass instead of trying to make ur drink! Security is a joke... The only exception is Marcus!! 2 fights, my wife got drink thrown on her and we just walked thru the door!! Don't go unless ur desperate  and nobody care, management don't give 2 fucks!! My wife got harrassed by security instead of the Muthafuckas fighting! Daniel, the management of security cares more about getting a $20 tip than taking care of his customers! I come to Vegas, quite often, never again will I ever come to Koi!! Please avoid it if u can!!!
