BBQ Whopper “from Miami” ?

I’m from Florida.  Is Miami, Florida well-known for BBQ sauce?
I haven’t lived in Florida (or even in America) for quite some time…but I don’t recall ever hearing about any “Miami BBQ“.

Well, anyway, Burger King in Japan has recently begun offering “BBQ Whopper Burgers…from Miami“.

Does Burger King offer this in America too?
Have you tried it? How does it taste? “Citrusy”?
