Open wide! Chicago Restaurant Week is back with 395 eateries offering dining deals from January 25 through February 7. For 14 belt-busting days, Chicagoans can cash in on special prix-fixe menus for brunch and lunch ($24) and dinner ($36–$48). Use the culinary event as an excuse to revisit an old favorite—like Blackbird, The Publican and mfk.—or explore a splashy new opening like Marisol, Le Sud or HaiSous. With two weeks to chow down, there's plenty of time to make a few reservations and check out some of the best restaurants in Chicago.
