Burger King Offers Free Fries and 'Green Sauce'

Not done celebrating St. Patrick’s Day? Burger King is offering free French fries and “green sauce” today.

That's right, this free offer is good at participating Burger King locations in Southern California on March 17 and March 18, and includes one free "value size" order of fries per person, per visit, according to the promotion. No purchase is necessary.

The “St. Paddy’s Sauce” is basically green ketchup, made by Heinz, said Burger King’s senior vice president of North America marketing in a statement.
