Nothing short of amazing.....
This is one of the few bars in town that I trust to make me a drink that consists of more then two ingredients (Ie. Jack n' Coke or Vodka Tonic). As a former bartender, I am very picky with regards to how my drinks are made. To me, cocktails are art and the bartender, the artist. Where else in town can you order a legitimate Pina Colada that is not pre-made and poured from a slushy machine. Where else in town can you order a legit Moscow Mule and they know exactly what you are talking about.
The bartenders at the Vesper Bar at Cosmo are a collection of the best of the best. And the best part? The prices were very reasonable for the drinks that were poured. Even if they had cost twice as much, I still would have been more then happy to pay the price for a five star drink.
