Big Mac or . . . Angus burger?

McDonald's (MCD) is now catering to true beef lovers. Patrons of the fast food chain now have a big burger option beyond the Quarter Pounder and Big Mac.

The fast food chain will start selling Angus burgers today, at about $4 each. The burgers are made with one-third of a pound of Angus beef and will be sold in all of the company's U.S. locations for the next several months.

"Customers are looking for great-tasting burgers at a value that only McDonald's can offer," spokeswoman Danya Proud said. "These premium burgers are a tremendous value compared to similar fast-casual and midscale offers."
