In a few episodes of Mad Men Season 2, Don Draper and Co. keep going to a restaurant in New York called "Lunesse". Its depicted as a really classy joint, a french place. Don takes the comedian and his wife there, and Don's wife gets really excited about going to such a fancy restaurant.
I know that in other episodes of the show, they talk about, and go to real New York establishments (Sardi's and P.J. Clarke's come to mind) but after googling Lunesse, I couldn't find any info.
Does anybody out there know anything about this place, Lunesse? Or is this possibly just a fictional Old New York establishment?
