Former Tudor House chef Jamie DeRosa has teamed up with Michael Reginbogin, his former Tudor House colleague and, as of this week, former general manager of Estiatorio Milos, to develop a "new concept under their recently established restaurant group, Social Dining Concepts, LLC," says a publicist. Vague, indeed. Sources tell us DeRosa was eyeing the space formerly known as Kim's Chinese Restaurant near Haven which, contrary to reports, is not going to be a reincarnation of the very dead 8 Oz. Burger. DeRosa, a new dad, has no comment other than the fact that his new spot/concept will be "kid friendly, of course." Stay tuned.
