You might wanna double check before digging into that lobster pasta.

Inside Edition recently tested lobster dishes at restaurants all around the country -- from mom-and-pop shops to big chains like Red Lobster -- and found that more than a third of them contain cheap seafood imitations in place of real lobster meat.

Beyonc would not be pleased about this.

For the test, Inside Edition ordered a lobster dish from each of 28 restaurants nationwide and sent the meat away for DNA testing .

IE said Red Lobster's "lobster bisque " contained at least part langostino , a smaller, cheaper lobster relative. Nathan's , of Coney Island fame, reportedly served a small fish called whiting in its "lobster salad sandwich ." And at one eatery in New York City's Little Italy, the "lobster ravioli " was said to be filled with nothing but cheese. Ick.
