Tom launched Craft, a restaurant known for its farm-fresh fare, in 2001. It was followed by Craftsteak, a steakhouse located inside the MGM Grand in Las Vegas in 2002.
Tom left the Gramercy Tavern circa 2006. Soon after, he launched Craft Los Angeles, Tom Colicchio’s Heritage Steak at The Mirage in Las Vegas, and other eateries. Tom is also the author of books like Think Like a Chef.
Most believe that Tom’s personal assets could be around $20 million, though the estimate is best taken with a grain of salt. Bearing in mind that Tom owns a restaurant empire and that he also stars in and executive produces Top Chef, it’s more than likely that he has enough to lead a very comfortable lifestyle.
