Foil wrap and all. I had always assumed it was created elsewhere, but it fills my heart with joy to know that my very own hometown was responsible for bringing the concept of a foil-wrapped overstuffed burrito to the world.
Living in Seattle years ago, I could not understand why it was so hard to find the burrito I knew and loved. They always insisted in on drenching these perfectly good burritos in sauce.
I'm going to call it a San Francisco burrito from now on. But maybe that's not necessary... there's only one kind of burrito in the world for me.
