Four courses for $250. Sound pricey? It won't sound so bad when you realize that the money's going to help kids with cancer.

Toque: An Evening with Chicago's Culinary Masters, a benefit for Children's Oncology Services, Inc. (COSI), goes down on September 10 at the Harold Washington Library Winter Garden, 400 S. State. Journalist and Tallgrass Beef founder Bill Kurtis emcees, while Michael Kornick (mk) acts as chef coordinator of a menu that also features Graham Elliot Bowles (Graham Elliot), Paul Kahan (Avec, Blackbird, The Publican), Art Smith (Table Fifty-Two), Chris Pandel (The Bristol), Randy Zweiban (Province), Mindy Segal (Hot Chocolate) and many more.

The fun starts at 6 p.m. with cocktails, a silent auction and featured chef's stations, followed by a sit-down dinner with wine pairings at 7:15 p.m. (there will also be a live auction at that time). For tickets and more details, visit www.onestepcamp.org.
