Citi Field

While they haven’t been as successful as their Bronx rivals in recent years, the Mets can certainly be happy about their newish stadium (and its amazing selection of food), which opened in 2009. Aspiring sluggers are invited to practice their swings and check the speed of their pitches on the Kiddie Field in the Mets' Fan Fest section. The hot spot also includes a dunk tank and an area where kids can get their photos snapped with Mr. Met. Diehard fans will want to wander through the Mets Hall of Fame & Museum—keep an eye out for the 1969 and 1986 World Series Championship trophies and the wall of team jerseys
