Here's something to roar about. A Tucson restaurant is about to serve up lion meat tacos. The FDA allows game meat to be served in restaurants as long as it's not from an endangered species. "Curious" customers are already lining up for reservations to chow down on the new tacos, which will sell for $9 beginning next month. The restaurant has already served tacos made with meat from pythons, alligators, elk, kangaroos, rattlesnakes and turtles, reports the Telegraph. The owner of Boca Tacos y Tequila says he'll try "just about anything we can get our hands on." (More Arizona stories.)
