Jack Lee (Lý Vinh Viễn) is a Chinese descent from Vietnam celebrity chef based in Ho Chi Minh City, Vietnam.
 He is often referred to in Vietnamese media as "đầu bếp Hollywood" (the Hollywood chef) or "đầu bếp của ngôi sao" (chef to the stars) in recognition of his background as private caterer for numerous Hollywood celebrities in the United States, which by association has advanced his public profile in Vietnam.
 At the height of his career while based in America, he was the executive chef of Baroness Kimberly Moore's "Echelon Club", a charitable lifestyle organization for high-profile individuals in Hollywood, and banquet chef at the Hotel Bel-Air.
 He has featured on a number of television series both in Vietnam and the United States, including "Rachael vs. Guy: Kids Cook-Off";, "Cutthroat Kitchen", "Food of the Stars" and "Food Paradise".
 He is currently appearing as a judge on Junior MasterChef Vietnam as well as Vietnam’s version of "My Mom Cooks Better Than Yours" on state-owned channel VTV3 and is also filming for the "Asian Food Channel".
 He has been promoting Netspace Culinary Academy in Vietnam with celebrity chef Anna Olson, and is a goodwill ambassador for the culinary charity K.O.T.O. (teaching employable food industry skills to Vietnamese street children).
Hugh's Chicken Run was a programme as part of Channel 4's 'Food Fight' series in which celebrity chef Hugh Fearnley-Whittingstall launched the campaign to encourage more consumers to demand free range chicken.

Beyond River Cottage is the fourth series of the Channel 4 programme that follows Hugh Fearnley-Whittingstall as he pursues the ideal of rural self-sufficiency as a farm-owner in Dorset.
