In the Bronx: Spend the morning at the Bronx Zoo Wildlife Conservation Park or the New York Botanical Gardens and then head to Arthur Avenue, the Little Italy of the Bronx, for an authentic Italian feast.
In Brooklyn: You can take a look at what's on at the always exciting Brooklyn Museum of Art, then get some fresh air with a stroll in nearby, lovely Prospect Park. Cap it off with a sandwich and a slice of cheesecake at Junior's on Flatbush Avenue. Or, head for Coney Island, whose face will change forever within the life of this guide. Go in the summer, hit the beach, the amusement park, the Aquarium, Nathan's Famous hot dogs, and/or maybe a Cyclones baseball game. It's a schlep, but one you will never forget.
In Queens: Take the 7 train, the International Express, to the Queens Museum of Art, on the grounds of the 1964 World's Fair, or the Louis Armstrong House Museum. On your way back, stop for a meal at any of the ethnic restaurants you will find within close proximity of the no. 7 train.
