The Margarita is America’s favorite cocktail. We like them so much, we’ll even pay more for them than other cocktails. In the world of casual dining, no one chain is closer aligned to the nation’s favorite mix of tequila, lime, and Triple Sec than Chili’s, which has a menu’s worth of variations, and is a (not so) guilty pleasure of drinks writers.

On March 13, for the second year in a row, the restaurant chain will celebrate its birthday by serving up “Presidente Margaritas” for the very special price of just $3.13, all day long.

In case you don’t speak Chili’s Margarita Menu, that’s a mix of Sauza Conmemorativo tequila, Patrón Citrónge premium orange liqueur, and Presidente Brandy, plus Chili’s secret sweet and sour mix it adds to all of its Margaritas. It’s the chain’s flagship mix, and this sweet ‘rita is even served on tap.

In case $3.13 margs aren’t enough to bring you out to your local Chili’s this Wednesday (what gives?), the restaurant is also offering the chance to win prizes. Tag @chilis in any Margarita and baby back ribs photo on social media, and you could win you a $313 gift card.

As with other popular drinks offers (see: Applebee’s), prices and availability may vary with location.
