This Italian restaurant in Port Angeles, Washington has a menu that features specialty pizzas and seafood. It appears in the first novel in the series, Twilight, as "La Bella Italia." In the book, Bella is 
saved by Edward from some local muggers (or maybe worse!) after she goes astray in her search for a local bookstore. After the rescue, Edward tells Bella's friends that he'll drive her back to Forks, and they decided to get some dinner at Bella Italia. It's Edward and Bella's first date.
Stephenie Meyer herself, the author of Twilight, New Moon, Eclipse, and Breaking Dawn, recently visited the restaurant, which has added the item that Bella ordered for dinner in the book (mushroom ravioli) to the menu.
I enjoyed this review by Dave Richards, who says Twilight by Stephenie Meyer has been good for him and his daughter:
Boxofficemojo.com is reporting that box office receipts for Twilight movie has now surpassed $150 million worldwide.
