Being a foodie can get pretty pricey. But once a year, for one magical week, Chicago's hottest restaurants dole out gourmet food at a fraction of the menu price so that even the most plebian diners can get their fill of beef cheek and duck fat. This year's gustatory smorgasbord runs from Feb. 1 through Feb. 10, during which time over 260 restaurants will serve lunches and dinners for a flat fee ranging from $22 to $44 per diner.
