Formerly a seedy "hostess" bar, Le Baron didn't bother to update its decadent cabaret décor (red banquettes, mirror ball, and baronial top-hat sign) when it opened in 2004—and it didn't need to. Models, musicians, and Oscar winners party until morning while indulging in the bar's classic cocktail: a mix of red fruits, champagne, and vodka called the Baron Deluxe. It's notoriously difficult to get in.
