Chicago Restaurant Week ends Sunday, but a few dozen restaurants will extend their $22 lunch, $33 and/or $44 dinner offers for a few more days, or more.

This will be the fifth straight year this has happened; Chicago restaurants, happy with the extra business that Restaurant Week brings, are eager to keep the momentum going. “Customer response has been phenomenal again this year,” said Corey Hardersen, food and beverage director at Geneva’s The Herrington Inn and Spa and its fine-dining room, Atwater’s.

So you can find those three-course lunches and three- and four-course dinners for a few more days, another week, the rest of the month — and two places are extending their deals through the end of March.

The catch, however, is that the part of the Chicago Convention & Tourism Bureau’s web page containing participants, menus and links to online reservations goes dark after Sunday (updating the extension or non-extension status of more than 250 restaurants would be next to impossible).

Following are the restaurants (60, at last count; we'll update) that have committed to extending their deals.
