If you're out and about and want a little snack, stop by your local Burger King today and tomorrow to pick up a free value size of their new onion rings! You can head over to their facebook page for more information; and even like them for a chance to win a $10 BK Crown Card.
I would recommend calling your restaurant before going to make sure they are participating.
The fine print: While supplies last. One value sized onion rings per person per visit at participating restaurants. Not valid during breakfast hours.
