I'm headed to LA soon for work and would like to experience some retro places while I am there. No doubt this is because of the influence of films like Chinatown, The Big Sleep, LA Confidential and even Swingers, but I definitely would love to hit up some bars with the cocktail culture / speakeasy vibe. We will be staying and working in the downtown area and in looking at Yelp, it appears the types of joints I'm looking for might include The Edison, Seven Grand or The Library Bar. I'm wondering if anyone here has been to those spots or if there are other places you would recommend? Thanks!
