I remember when the motto "Have It Your Way" first appeared in advertising for Burger King. The premise was that it was rare that one could go to other fast food burger places and ask for tomatoes, lettuce, bacon, or mayonnaise on your burger. That was many years ago, and the fast food landscape has changed dramatically.
We are now in the age of customization. Places like Chipotle' and Moe's offer you the choice of what you want in a fast food setting.
Burger King is now heading into a territory that I could not imagine...Tacos.
