WHO COULD EAT ALL THAT?

The chains with free food prizes and the people (600,000!) who want them.
Next month, Denny's will pick the winners of its "Grand Slam for a Year" promotion. Each can order 52 servings of a Denny's Grand Slam breakfast, or two eggs, two strips of bacon, two sausage links and two pancakes. That's a stack of pancakes four feet high, with 17,680 calories, not counting the syrup.
Denny's Corp. hopes the contest brings more customers through the door, especially since people can't necessarily eat this much themselves and often bring along their friends. "Consumers still respond to free," says John Dillon, the company's vice president of marketing.
Doughnuts, popcorn chicken and foot-long sandwiches are free for the taking, too. Among the chains with giveaway contests and other promotions: Subway, Chick-fil-A Inc., Krispy Kreme Doughnuts Inc. and KFC Corp.
Giveaways are an inexpensive way for companies to stretch their marketing dollars during the recession. Contestants also tend to brag about the sport of entering free food contests, something that's easier than ever with social media sites like Facebook and Twitter. That spreads the restaurants' marketing message even further.
Out of the 600,000 people who entered the Denny's contest, 450,000 opted to join the Denny's Rewards program, which regularly emails updates on new menu items and specials. Denny's bets these emails will draw more loyal customers to its 1,545 restaurants, Mr. Dillon says.
