Bacon and cheese too old-hat for you? Wendy's has a solution: Its new burger toppings include caviar and lobster. Unfortunately, you'll have to head to Japan to sample the offerings, and you'll have to do it quickly—the burgers are part of a limited-time offer. They follow Wendy's re-entry into Japan in 2009, when the company debuted a burger with foie gras and truffle sauce; both burgers will run you about $16. Fast-food chains like the struggling Wendy's are increasingly looking for opportunities abroad, the Los Angeles Times notes.
