Chronic Tacos, the California-inspired Mexican grill, is celebrating National Taco Day in a big way – all lunch customers will get one free taco with a code word announced the day before on Chronic Tacos social media.

To redeem the free taco, customers must follow Chronic Tacos on Instagram or like the Facebook Page, and watch out for the code word posted the day before and present it to a team member. Offer excludes steak, fish, and shrimp tacos.

Founded in 2002, the California-based company has more than 50 locations operating across North America and is committed to serving only the highest quality with fresh ingredients and all-natural meats.
