[16] Voltaggio was quietly planning a smaller restaurant around the corner, a sandwich shop called ink.sack, while publicly developing and readying ink.
[17] Voltaggio designed and built the shop himself [18] and surprised the culinary world when he opened the small restaurant with little notice or fanfare.
[19] From August 11, 2011, until 2018, he owned and ran the ink.sack, a sandwich shop which had two locations, including one on Melrose Avenue (in West Hollywood) and one on Sunset Boulevard.
Top Chef Head Judge Tom Colicchio said of Voltaggio, “Out of all the cooks that have come through the show, Michael is the most talented—both from a sensibility and technical standpoint.
[29] On March 14, 2022, a new show started airing on the Food Network called The Julia Child Challenge, on which he's a judge along with Antonia Lofaso.
Voltaggio has three daughters; Olivia and Sophia, with ex-wife Kerri Adams, and Echo Monroe, with wife Bria Vinaite.
