Tucson's Boca Tacos y Tequila made national news last week when owner Bryan Mazon announced his plans to serve lion meat street tacos by pre-paid order on February 16.

Now, he's called off his plans after the restaurant, his family members, customers, and vendors received "many threats."

Earlier installments of Boca's Exotic Taco Wednesdays have featured such meats as rattlesnake, alligator, elk, and kangaroo.
