Vertigo Sky Lounge at the dana Hotel

Designed to feel like a penthouse party at your coolest friend's posh pad, this indoor-outdoor bar hopes to evoke a cocktail-party vibe. Outside, expect a glass perimeter giving way to city views and a firepit to extend the alfresco season, plus curvy wood benches and movable ottomans on which to perch. Besides the a sleek open area filled with leather couches and shiny silver side tables, two tucked-away nooks caught our attention: The dim-lit screening room, which'll play retro flicks, and the communal bathroom area, where you can ask for a date over the Dyson hand dryers.
