The Midwest is known for being the setting for all three Jaws movies and a bevy of delicious culinary creations. Today's Groupon follows cravings to the metropolitan middle of the nation with $25 worth of Chicago grub for $10 at Wolffy's Place on the corner of Ninth and Market. You and a friend can dine on ribs, dogs, and Italian beef like high-society gangsters at a 1930s joint.
