Here is the excerpt that mentions horse meat:
Armed with a hidden camera, the two women captured the waitress serving them whale and horse meat and identifying them as such, a federal criminal complaint said. A receipt from the restaurant at the end of the meal identified their selection as "whale" and "horse" with the cost -- $85 -- written next to them.The sei whale that was served is considered endangered, so that is certainly a good argument for not eating that. But horse meat? EAT UP.
