Okay, so it may not, in fact, be the world's largest, but at more than 40,000 square feet, it's Vegas's largest souvenir store. And although it carries most of the usual junk, this peddler of pop-culture kitsch also stocks some most unusual junk. A pair of fuzzy pink dice? Check. Blinking "Welcome to Fabulous Las Vegas" sign? Check. Elvis aviator sunglasses complete with black sideburns? Check. How about a battery-operated parrot with a potty mouth or 3-inch plastic slot machine that squirts water? They're all here, seven days a week, open till midnight. As the store likes to say, "if it's in stock, we have it."
