This weekend’s Expo promises the green-curious more info than they knew they ever wanted on local, sustainable farming, shopping, cooking, eating . . . you name it. Friday’s programming is geared toward industry folks: farmers, chefs, buyers, distributors. Friday evening there’s a fancypants reception ($75 in advance; $90 at the door) benefiting local farmers and businesses. Your ticket gets you food from Chalkboard, First Slice (pdf), NoMi, Cousin’s Incredible Vitality, and others (including the still-unopened Crust). There’ll also be wine tastings from Illinois wineries, Goose Island beer, cocktails courtesy of Butterfly Social Club, and organic martinis made with Rain Vodka.

Saturday’s food festival is designed for consumers and includes exhibits from farmers and related types, a farmers’ market, film screenings, events for kids, demos by local chefs, and workshops on stuff like “Eating Organic on a Dime” and “Hot Topic: Urban Agriculture.” The event’s organized by the nonprofit group Sustain, which just unveiled a handy map to the delivery areas for ten CSAs operating in and around Chicago on the Family Farmed Web site. Admission each day is $20 ($15 in advance, and two-for-one if you buy online); it’s at the Chicago Cultural Center, 78 E. Washington, from 9 AM to 6 PM Friday and Saturday. See you at “Sustainable Seafood.”
