There's no police station, but you can get her likeability up by collecting wallets and calling her over to your house to give them to her. she also increases likeability by giving her food. so once she is happy enough with you, take her out to eat a few times to make sure she will do whatever you want, then do whatever you want.
also, Bobbie, only takes food until she is comfortable enough to go out to eat, then she will do what you want. buy a few drinks and give them to her while you are in the ally. she will then get just enough likeability to allow you to take her out to eat.
