Lobel's Culinary Club, August 17, 2012 [2]: "Steak Diane is among those popular dishes in ubiquitous cosmopolitan, Continental-style restaurants of the 1950s and ’60s that combined high style with leather banquettes, white-linen table cloths and dishes of American and European influences, a bit of theater and dramatic preparation."

Leah Koenig, "Lost Foods of New York City: Steak Diane", Politico, March 14, 2012 [5]: "Lost Foods of New York City is a column that celebrates the food and drink that once fed the city, but have disappeared....

What better time, then, to celebrate steak Diane—a dish so quintessentially retro-glamorous, it might as well be called steak Don Draper."
