The eleventh season of Top Chef debuts on Bravo on October 2, and while there aren't any chefs currently working in Arizona on the roster, there is one chef with a (more-or-less) local connection, Ramon Bojorquez, from Rio Rico:
Ramon Bojorquez is the Sous Chef at Nine-Ten, an upscale farm to table restaurant in downtown La Jolla, California. Ramon is of Mexican descent, born in Rio Rico, Arizona, and was professionally trained at the Scottsdale Culinary School. He grew up watching his grandfather cook, and carries a considerable amount of Mexican, Spanish, and Thai influence in his cuisine. He has traveled the world, from serving as a stage in Spain to fighting Muy Thai professionally in Thailand.
