Double Mushroom Swiss
Gentle…velvety…bliss…
Can't get enough of that heavenly creamy taste? Go for double the goodness! Melted Swiss cheese on two flame-grilled beef patties, topped with BK's special mushroom sauce, served on a sesame seed bun. Twice the velvety goodness in every bite.
The sandwich is always prepared exactly how you like it - with cheese or beefacon™, with extra onions or without tomatoes.
Your way to order the WHOPPER® sandwich is always the best way.
