The atmosphere here is exactly what I expected..very Mad Men-esque. I had the 18 Liberty, the couple next to us had each other's throats...I think mine was better. For as swanky a vibe this place has, I expected classier dress and behavior from the clientele. In case you were wondering, jeans are acceptable, so don't worry about a dress code. The prices are shockingly average compared to what I expected--$8-15 for a cocktail.
