t's a secret even to us how such sophisticated breakfasts come out of the tiny Art Cliff Diner, prepared by a former chef to the stars. Try the avocado, salsa, and chorizo breakfast tacos and codfish cakes with hollandaise sauce. The ingredients come from local farms and the restaurant's own herb garden, the fish is straight off the boats, and there's a kids' menu that adults will want to order from, too, with green eggs and ham and root-beer floats.
