I don't know where this would belong in, food or books.

While you were reading a book and it mentioned the name of a food, would you crave it?
For example, if a book had a sentence that said "Bob ate a double scoop vanilla ice cream sundae with a cherry, chocolate syrup, and whipped cream for dessert on Friday" would you crave that?
Because uhh.. for me it's like a habit
This book I was reading kept on mentioning grapes and I had to go to the supermarket to buy grapes =]
