The most low key of the three main bars of Cosmopolitan, Vesper is relatively small, and that’s how we like it. While tourists might be cramming themselves into the Bond and Chandelier bars, this is where you’ll find savvy locals and hotel executives unwinding after their days (we wonder if it’s because of its close proximity to the parking garage elevators). Named for an obscure cocktail created by James Bond in Casino Royale, the focus here is on other cocktails of the same ilk: classic and with a twist. The music can get a little loud on weekend nights, but the steady stream of stumbling club-goers through the lobby make the people watching pretty hilarious. Vesper is open daily 24 hours.
