Charity of the Month
At Burger 21 we have long obsessed over the quality and flavor of our burgers. This obsession for creating the best burgers possible extends to our local communities who also share in our #BurgerLove. Since 2009 Burger 21 has donated more than $130,000 to local community organizations. Burger 21 is proud to support local community fundraising events and programs by hosting and by donating 10% of our sales to our charitable partners for these Spirit Events.
