Come Friday, folks passing by the Willis Tower are going to hear a lot of people declare that they are the true Sausage King of Chicago. The skyscraper's management, as part of a city-wide celebration of "Ferris Bueller's Day Off" 30th birthday, are contributing with the Sausage King of Chicago Abe Froman food cart parked outside of the building on Wacker Drive.

From noon to 2 p.m., the cart will serve hot dogs and other items every other Friday starting this week and through Aug. 26. Hubby's Dog House, a three-cart operation normally found around Lincoln Park, will sling the sausages in a cart transformed with Hollywood bling to recognize John Hughes' iconic movie released in 1986.

Don't remember the line from the movie? Matthew Broderick, who plays Ferris, declares himself as Abe Froman so he could secure a table at a posh fictional Chicago French bistro, Chez Quis. That schtick wouldn't work in this day and age with Tock and OpenTable.

The Willis Tower isn't the only one with a food-related celebration of the flick. Virgin Hotel Chicago is offering a special menu at Miss Ricky's from Friday through Sunday. There's the Sausage King of Chicago Roll (a traditional banger, wrapped in stuffed pastry with curry sauce and giardiniera aioli) There's also Buckledown Brewing Co.'s Ferris Bueller Beer.
