News: Burger King Debuts New A.1. Ultimate Cheeseburger and Mushroom & Swiss Big King

Burger King fights back the midsummer lull with the introduction of two new burgers: the A.1. Ultimate Cheeseburger and Mushroom & Swiss Big King.

The A.1. Ultimate Cheeseburger features a full half-pound (precooked weight of course) of flame-grilled beef in two quarter-pound beef patties plus thick-cut bacon, American cheese, onions, and A.1. Thick & Hearty steak sauce on a toasted Artisan bun (the same one you find on their premium chicken sandwiches).

The Mushroom & Swiss Big King is a new variation on their Big Mac-clone and features a club-style 3-part sesame bun filled with two flame-grilled beef patties, Swiss cheese, sauteed mushrooms, and mayo. They've done the mushroom and Swiss combination before and it turned out pretty well, but we'll see.

Both burgers are available for a limited time only at participating BK restaurants. No word as of yet on pricing, but I would hazard a guess of $3.99 for the Mushroom & Swiss Big King (and a possible add to their ongoing two for $5 deal) and ballpark the A.1. Ultimate Cheeseburger between $5 to $6.
