Throughout the years, hamburgers have endeared themselves to a variety of food lovers. Restaurants across the country compete for who can create the biggest hamburger, and culinarians write books devoted to cross-country road trips in search of the very best burger. You can find hamburgers in tiny hole-in-the-wall diners and on the menus of Michelin-starred restaurants. In 2005, Las Vegas restaurant Fleur de Lys outdid themselves by creating a $5,000 hamburger served with champagne. Seems a bit silly to me, but it does prove the widespread appeal of this simple and tasty sandwich. Even now they continue to evolve. Next, it appears that burgers will be grown in test tubes. I shudder to think.
