Mr Au is a Chinese restaurant in Westminster, London, next to Leicester Square Underground station. It's not the Ritz, but it does have the particular redeeming feature that you can have all you can eat for £4:50, and pretty much ever non-alcoholic drink is £1:00, including large pots of green tea. The menu is always the same: sweet and sour pork, spicy beef, noodles, vegetable soup, egg fried rice, chicken wings, spring rolls, and vegetable stew. The Mr Wu chain are virtually identical.
