For those non-diet conscious carnivores who consider a half-pound hamburger a mere appetizer, the Upper Deck Restaurant at the Vegas Club Hotel and Casino in Downtown Las Vegas has just the hamburger: the 9 pound "Big Daddy Barrick Burger." Served with a bun 12" in diameter, a half head of lettuce, two tomatoes, two onions, four pickles, mayo, mustard and 12 slices of American cheese, the burger big enough to feed a softball team is available for $49.99. If one person finishes the burger within 24 hours, it is free!
