There is an unofficial Mad Men cookbook called The Unofficial Mad Men Cookbook: Dine like Draper and Drink like Sterling: Recipes to Satisfy a Mad Men Appetite written by Judy Gelman and Peter Zheutlin.
Here is the review from goodreads-
The appeal of AMC's award-winning period drama Mad Men, shortly to begin its fifth season, lies as much in its painstaking portrait of 1960s America as in the emotional lives of its characters. In The Unofficial Mad Men Cookbook, Judy Gelman and Peter Zheutlin explore the show's culinary backdrop, from the food we see on the table at Sterling Cooper power lunches to the dishes Betty serves at Draper dinner parties. With more than 60 recipes, photos, and other images all drawn from the period in which Mad Men is set, The Unofficial Mad Men Cookbook is perfect for appreciating the role food and drink play in the hit series or for throwing your own historically accurate Mad Men-inspired cocktail party.
* Find out why Betty might have chosen her "Around the World" dinner party theme; plus why Don’s Heineken ad campaign would have been so well-received by the public; and try a gazpacho from Spain, using a recipe Betty herself might have.
*Learn why Sardi’s, the restaurant where Bobbi Barret and Don celebrate selling her husband’s new pilot, was a likely location for post-TV deal celebration, and make Sardi's famous steak tartar for yourself.
Includes a color photo insert of 16 dishes, plus additional black and white photos and other images of bars, restaurants, and food advertisements from the 1960s.
Looks like it's worth checking out. I wonder if my library has a copy.
