Open calls are scheduled in Los Angeles on Saturday, June 30th, and in Chicago and New York on Saturday, July 14th. Possible contestants are asked to bring "food/ingredients to be finished and plated once you enter the audition room," as there'll be no kitchen in which to finish or warm dishes. The 13-page application asks about everything from motivation for doing the show to criminal background information and notes that "it is OKAY if you are not a professional chef." So, whew.
Don't live near a casting call city but still want to maybe make a fool of yourself and maybe get yelled at by Anthony Bourdain? Just apply by video.
