A bigger big mac?

FOX's Rich Denison reports:

Americans might someday see a bigger and smaller version of McDonald's 'Big Mac'...

As McDonald's works to revive its business, it's test marketing a 'Grand Mac,' and 'Mac Jr.' in Central Ohio and Dallas.

The 'Grand Mac' is made with two one-sixth pound burgers, special sauce, lettuce cheese pickles onions on a sesame seed bun...

The 'Mac Jr.' essentially a single-layer 'Big Mac' easier to eat on the go, according to officials with the fast-food chain.

How the new burgers fare in the test markets will determine whether there's a national roll-out.
