Butcher Rob Levitt’s status as a Good Food leader in Chicago crystallized after he and wife Allie opened The Butcher & Larder in 2011. But Rob also is an outstanding chef who met his wife Allie while they were training at New York’s Culinary Institute of America. And it will be in that chef role that Rob will be taking part in the Frontera 30th Anniversary Celebration, a joint fundraiser for Chef Rick Bayless’ Frontera Farmer Foundation and FamilyFarmed, which will take place on Sunday, April 30 at the Art Institute of Chicago.
