Today, Feb. 22, marks National Margarita Day, and Taco Cabana is celebrating with an "All-Day Happy Hour."

The fast-food chain is offering $3 margaritas from open to close Thursday, as well as $2 off any size quesadilla.

Taco Cabana is also marking the national holiday by bringing back their limited-edition Mango Margarita, complete with a chili lime rimmer. The company says the special margarita will be available while supplies last.

The restaurant chain emphasizes that the offer is only available Thursday, February 22, and the discount on quesadillas does not apply to the brisket quesadilla. The deals are also not available through online ordering.
