Both Parasol Up and Down are great places to go to in order to start a night. I usually go there with friends before hitting one of the clubs at Wynn/Encore or while counting down the time to a reservation at one of the many restaurants at Wynn/Encore. I prefer Parasol down because it's slightly quieter and has a more personal feel, Parasol Up however is open later and is more accessible (not sure if its 24 hours though). In addition to this, both bars have a great selection of spirits to choose from, including brands that aren't available at other higher end bars including Death's Door Gin.
