In the six months since it launched Exotic Taco Wednesdays, Boca Tacos y Tequila has served up python, alligator, elk, kangaroo and rattlesnake.
Frog legs, turtle, duck and Rocky Mountain oysters have also made appearances.
"We've done just about anything we can get our hands on," said owner Bryan Mazon. "Every Wednesday we do something a little bit different."
Last week he announced on Boca's Facebook page that the UA-area taco shop was accepting prepaid orders for African lion, to be served on Feb. 16. Orders must be placed by 3 p.m. Feb. 7.
"I've gotten a lot of questions, like if it's legal," said Mazon, adding that a few lion tacos have been reserved so far. "We're still a month out, too."
According to the Food and Drug Administration, lion and other game meat can be sold as long as the species isn't endangered.
