As culinary competitions go, Chowderfest is soup makers' answer to the Super Bowl. This annual event takes place at the end of Harborfest, attracting more than 11,000 revelers to City Hall Plaza for a full day of dining, children's activities, strolling entertainment and community camaraderie. Contenders are sure to include Captain Parker's Pub and Restaurant, Turner's Seafood Grill and Market, the Atlantic Fish Company and the Bay State Chowda Company, and Bostonians and visitors alike are encouraged to cast their ballots, working their way through over a thousand gallons of entries to select this year's winner. -- Julia Clinger
