What does the woman want to know?

W: My parents are coming to see me this weekend, and I want to take them to a nice seafood restaurant because my father is crazy about seafood. Would you happen to know a good place in town by any chance?(47)
M: Sorry, I don’t eat seafood because I am allergic to it. However, you might want to ask Jeff.(48)He apparently knows all the nice places in town. I heard it’s a hobby of his to find and try eating at new restaurants.
W: Really? That’s very interesting. I’ve heard of people who do that, but I didn’t really think I would know anyone.
M: Yeah, he says he is going to write a book on it someday.(49)
