Amazing experience! First time staying at The Cosmopolitan. Our room was being serviced and needed to kill some time. Wandered in to the Vesper Bar and had the good fortune of having Jayme and his fellow bartender (sorry, didn't get his name) engage us with great conversation and wow us with fine craft cocktails. We were not expecting such a high caliber of service from what would normally be considered a "Lobby Bar". Great job gentlemen.
