We are visiting Chicago in May and are planning our eating extravaganza --- specifically, we are looking for good and interesting vegetarian fare. Places we've been and loved are the Green Zebra (of course!) and Cafe Lula. We'd love to get some ideas on new places to try, anything from diners for brunch (is the Handlebar any good?) to adventuresome for dinner (I read about someone getting a veggie tasting at Moto). Any suggestions?
