A.1.® HALLOWEEN WHOPPER® SANDWICH AT BURGER KING
It is a limited time offer at Burger King and described on their website as:
” With A.1.® flavor baked into the black bun. The sandwich is a ¼ lb.* of savory flame-grilled beef topped with melted American cheese, ripe tomatoes, crisp iceberg lettuce, creamy mayonnaise, A.1.® Thick and Hearty Sauce, crunchy pickles, and sliced white onions on a soft sesame seed bun with A.1.® flavor baked into the bun”
I liked the burger and the bun had a little tang to it, but felt it needed more A1 sauce on the burger itself, but settled for ketchup. If you order would suggest requesting with a generous helping of A1 on the burger or adding ketchup.
