I have friends visiting from Washington, DC. They're lovely people but pretty uptight and I'm far more free spirit. Would love to introduce them to LA dining at its finest. Any suggestions? I have a couple of thoughts but would like to hear from true LA foodies. Your favorite spots in LA where the decor is hip and happening or elegant or romantic -- doesn't matter -- so long as it's a memorable night out for food and ambiance. Ideas for lunch or dinner are appreciated. Many thanks.
