So do you remember last year's tussle between Lay's and Jays? Where Jays took Frito-Lay to court, disputing their ads that Chicago prefers the taste of Lay's potato chips over Jays? Well, it looks like Lay's might have some more ammo to boost their claims: the Sun-Times reports on a new snack food survey conducted by Chicago-based Information Resources that indicates Lay's outsold Jays in Chicago, $17.1 million vs. $13.3 million, based on 2005 supermarket sales data. The survey also indicates that cookies are the top-selling snack food in the city, with Oreo cookies #1 here and nationwide.
