Sichuan chef Peter Chang has provoked Atlanta foodie hysteria since opening his first restaurant here. He came to the United States from China to be chef at his government's Washington, D.C., embassy in 2000. Then he hip-hopped around the South, never staying more than a few months at a restaurant. He landed at Tasty China in Marietta in 2006, turning a strip mall joint into a mecca. He left. He came back. His wake is littered with love letters, including one by Calvin Trillin of the New Yorker. Now the beloved is at a new place, Peter Chang's, opened by Tasty China's owners. He claims he's staying. And money grows on trees. Hurry there before the inevitable occurs.
