Flatiron Lounge 37 W 19th St New York NY 10011 USA http://www.flatironlounge.com/ (Map) Citysearch Stepping into the Flatiron Lounge is like stepping back in time. Appointed in an art deco motif, it presents it's customers with a taste of what a 1920's speakeasy may have felt like, with two noteable exceptions. You don't need to know a secret password to get in, and the drinks are fabulous!
