What's new at the Golden Arches? A bigger burger.

FOX News Radio's Bill Vitka reports.

McDonald's is beefing up its menu, adding premium sirloin burgers for a limited time in a bid to revive sales.

Its an upscale one-third-pound patty available in three versions: bacon and cheese, lettuce and tomato and a steakhouse version with mushrooms, onions and cheddar.

It'll be served -- on wood -- like a cutting board.

It's the second time around for the bigger burger, an Angus burger -- that had been on the menu -- was pulled 2-years ago, considered too pricey.

The new burger will be priced around $5. The promotion starts May 12th and runs til the end of June, but some markets are expected to begin serving the new burger sooner.
