Burger King introduced this menu item to compete with McDonalds Big Mac, which they had previously criticized in their advertising for having too much bun and for its "secret sauce". It is almost identical to the Big Mac except for the fact that the meat is flame broiled instead of fried, and it does not have the middle bun. Just like the Big Mac it has two beef patties, sesame seed bun, lettuce, onion, and contains a sauce that tastes very similar to the secret sauce on the Big Mac. Personally, I don't like them very much. They taste even worse than a Big Mac, which don't really taste all that good to begin with. Avoid.
