Citi Field has been the home of the New York Mets since the spring of 2009. In addition to the action on the field (2.5 acres of 100% Kentucky bluegrass), there's plenty to see and eat here. Open on game days, the Mets Hall of Fame and Museum, located next to the rotunda, has an extensive collection of team memorabilia on display, including Tom Seaver's 1967 Rookie of the Year award. During baseball season, the stadium is also known for its stellar food from top-notch chefs, who serve burgers and hot dogs with gourmet fixings at Shake Shack, slow-cooked pork tacos at El Verano Taqueria and lobster rolls at Catch of the Day. The USTA Billie Jean King National Tennis Center, a haven for tennis lovers, is a short walk away. Although the center is most famous for hosting the US Open, its indoor and outdoor courts are open to the public every day of the week, 11 months a year, for private and group lessons, open court time and heart-pumping Cardio Tennis classes.
