All they have is just a pokmon center, but It's supposed to have a lot of buildings and towers.
you need to get people from white forest to your black city and then the bulidng start returning
You must have taken too long to finish the storyline.... The longer you take the less things your black city/white forest will have.
This has already been asked here.
Quoted form Darmanidude
To get people back you have to go in to a white entralink and go to white forest. Then talk to people and some people will follow you back there. It unlocks stores and trainers in black city.
