Like Las Vegas, the allure of L.A. -- for better or for worse -- is undeniable. Los Angelenos know their city will never have the sophisticated style of Paris or the historical riches of London, but they cheerfully lay claim to living in the most entertaining city in the United States, if not the world. It really is warm and sunny most days of the year, movie stars actually do live and dine among the commoners, and you can't swing a cellphone without hitting a roller-blading blonde at the beach.
