Cinnamon's Restaurant   Inside Kailua Square, just off Uluniu Street, this family-owned restaurant gets the nod from residents for chef-partner Carsie Green's comfort food (eggs Benedict, loco moco omelets, meat loaf, baked spaghetti) and the considerate service (coffee and a newspaper while you wait for a seat). A favorite neighborhood breakfast spot, Cinnamon's has daily pancake specials such as blueberry-banana sprinkled with powdered sugar.  315 Uluniu St., Kailua. 261-8724. 7 a.m.-2 p.m. Sundays-Wednesdays 7 a.m.-2 p.m., 5:30-8:30 p.m. Thursdays-Saturdays.
