Why do the prices differ so much? We compare what each menu calls the same dish, and menus are not identical: portion, cut, sides and the kind of room you are sitting in all ride on the price, and none of that shows up in a number. Part portions and half sizes are kept out of this comparison, and a chain charging the same at several addresses is counted once, so the spread above is between genuinely different kitchens rather than the same one repeated.
