Nah he’ll be aight. I’d highly recommend going down to Flatbush Ave station (right near Brooklyn College) and walking down Flatbush towards Prospect Park. One of the most densely packed black neighborhoods in America, filled with black American/Caribbean culture. Grab some Guyanese food from Joy & Snook on Norstrand Ave or Bakes & Things. They got a Kennedy Fried Chicken on the strip too
Once you finish the strip, you’ll be right in Prospect Park. Central Park is more iconic but Prospect Park has a charm of its own and is a dope park to spend sometime in.
Also would recommend going up to 125th street station in Harlem. Get off and just walk around the neighborhood. Check out the Apollo, some of the beautiful brownstones and grab something at Amy Ruth’s or Sylvia’s
Can’t go wrong heading over to Dumbo and hitting Brooklyn Bridge Park. Some of the best views in the city and they got a Shack Shake there, NYC staple.
