Burger king is certainly still better for burgers where I've lived. But I think it has more to do with mcdonalds being worse than most places, than burger king being much better. Also always fucking dirty at burger king.
But the answer is... Jollibee. The local favorite chain here, disgusting shit burgers. The meat taste of fish, they put pineapples in some of them which is just wrong.

and to make it worse, as you are trying to eat your very shitty burger, they sometimes like to bring their mascot out, who will dance to techno music as you are eating. So you would think this is something that appeals to kids mostly... But all the adults here love it.
