Since the Golden State Warriors won a game in Cleveland last night, the chain is set for the freebie on June 21, 2016, from 2 to 6 PM local time. The promo is limited to one free Doritos Locos Taco per person at participating locations.
As I mentioned earlier, the "Steal a Game, Steal a Taco" free taco was more a question of when rather than if.
