You know you have a selective palette when you order a caviar burger. I did a quick Internet search which revealed the Caviar Burger is an actual menu item at Serendipity3, located in New York.

The same restaurant known for its $25,000 dessert does indeed serve such a luxury burger, complete with cucumber slices and sour cream, for a mere $17.50 US. While it isn't the exact burger pictured here, I'm sure the concept is not lost.

With this opulent dish being a reality, it remains to be seen whether this idea will become marketed as the new Western sushi, or the Asian burger.
