What would you put on the ultimate burger?

I know of no other dish that is so hated, berated and debated (and loved, adored and praised - but that doesn't rhyme) as the humble burger. The term "Hamburger" comes from Hamburg, which is (if you didn't know) Germany's second largest city. According to Wikipedia, lots of people from Hamburg emigrated to the US, bringing with them the "Hamburg steak". The first printed menu in America to list hamburger was a 1826 menu from Delmonico's in New York.
Since then, it has evolved not only into a fast-food staple but also a standing menu element for gourmets to deconstruct/reconstruct. Personally I'm more inclined to fish&chips, but that's subjective to say the least... Anyway, I've noticed a trend in burger reinventions recently. Most notable is this giant from New York's Wall Street Burger Shoppe.

At $175 the Richard Nouveau as it's been christened contains 10 ounces of Kobe beef, foie gras, exotic mushrooms, cave-aged Gruyère, fresh truffles, a brioche bun as well as a total of 750 milligrams of gold. Apparently someone has developed a taste for these artery-busting bombs of gluttony, because they have a standing order of two a week. To each his own, as they say, but I can't help but wonder what one orders to drink with this. A diet Coke? Or Dom Perignon? You tell me. And while we're at it, what would your ultimate burger look like?
