Cheers! Chili’s Presidente Margarita celebrates its 21st birthday, as expected, with (what else?) drinks. To celebrate the margarita being all grown up, on Wednesday, October 21, customers can enjoy a Presidente Margarita for $5 and chips & salsa for 21¢ at participating locations. (For non-drinkers, you can order the chips and salsa by itself — no margarita purchase required.) The Presidente Margarita is the chain’s #1 selling drink. Not just any margarita, the signature beverage includes Presidente brandy, an ingredient aged for three years in white oak and not found in most margarita recipes.
