N.Y. grocer sold lobster salad - with no lobster

The lobster salad at Zabar's grocery has been an institution in New York City for at least 15 years. They've sold thousands of pounds of it.

But it took a tourist and a New York Times article to uncover a surprising truth - plainly obvious on the ingredients list - that there's no lobster in the lobster salad.

The main ingredient, CBS News' Betty Nguyen reported on "The Early Show," is described on the package as "wild fresh water crayfish," which store owners say is in the lobster family.

However, to avoid confusion, they've changed the name to "seafare salad" - even though, Nguyen added, freshwater crayfish don't come from the sea.
