Going Green in America's Cities

Where to stay: As part of the Kimpton group, the Monaco (866/610-0081; monaco-chicago.com) has a green procurement program, as well as a variety of social and environmental benefit and impact programs such as Dress for Success, Red Ribbon Campaign, and local coat drives.

Where to eat: Chi-town made big news when it banned foie gras from restaurants, but restaurants like Rick's Bayless' Topolobampo (312/661-1434; rickbayless.com) have been at the top of the eco-food chain. One of the forerunners of the sustainable food movement, Rick's place offers a sustainable seafood bar featuring organic farmed shrimp, oysters, and lime-marinated bay scallops.

How to travel: Chicagoans "El" their sustainable selves around town, but those who need some green freedom can rent a Vespa at Windy City Vespa (773/276-5200; windycityvespa.com)

Green activity: In the concrete jungle, escape to the green spaces of the 24.5-acre Millennium Park (312/742-1168; millenniumpark.org), where you can take the self-guided audio tour for free.
