Burger loyalties

My hamburger loyalties are torn. On the one hand, I feel that I should stay true to the burger that nurtured me with multiple cheeses, jalapeno-kick, and a somehow exquisitely perfect bun during my fledgling days as a college student in Milwaukee. On the other hand, the loins of my mouth now yearn for a burger coupled fantastically with a fried portabello mushroom that runs grease and cheese all over my lap when I bite into it. I would never eat one exclusively over the other, but I feel the need to have a favorite, and it's ravishing the depths of my soul.
