The kitchens are blazing as firefighters work to open restaurants with the people closest to them. College fraternity brothers John Sierp II, firefighter and owner of a catering company in Brooklyn, N.Y., and Jeffrey Waters, assistant general manager at an Atlanta restaurant, live far apart but their love of food and the restaurant industry has kept them bonded as they create their seafood and steakhouse restaurant called Seven-20. Twin brothers from Santa Rosa, Calif., Michael Graves, sales manager for a local trucking company, and Kris Graves, firefighter, use each other's strengths to help them open Enigma, serving comfort food classics with a touch of class.
