Japanese Kobe beef is considered the tastiest beef money can buy: a single steak can cost as much as $600. But an INSIDE EDITION investigation found that while some menus advertise Kobe beef, they are actually serving up meat of lesser value. Kobe beef, which has a marbled appearance, comes from pure-bred cattle raised on a special diet in Japan. The meat can cost $55 dollars an ounce, and only 400 pounds get shipped to in the U.S. each month, according to Kobe beef distributor Brent Nakama. #InsideEdition
