LOS ANGELES, March 12 — Hundreds of pounds of caviar, black truffle, sushi and tomahawk steak have been shipped to Hollywood for the traditional lavish Oscars after-party this Sunday.

They will be washed down with thousands of bottles of tequila and champagne at the Governors Ball, where newly minted Academy Award winners get their statuettes engraved while fellow A-listers feast, dance and gossip.
