Cost: $3-$7, children under 12 free

Organizer: The Copernicus Foundation

What to expect: Live entertainment (four stages), vendors, polka dancing, food, cooking classes and more.

Why to go: They say there are more Poles in Chicago than there are in Warsaw. Whether or not it's true, you've gotta support.

Additional info: The proceeds benefit The Copernicus Foundation, a local cultural organization. Polish Mass will be celebrated by Bishop Jakubowski and Father Dzieszko at noon on Sunday. Festival organizers claim to have hosted over a million visitors in the last quarter century, including such dignitaries as George H. Bush, Dick Cheney and Tipper Gore, so expect to wait in line for your kielbasa and pierogi.
