Let me give you an example: story : Honolulu is the capital and largest city of the U.S. state of Hawaii. It is an unincorporated part of and the county seat of the City and County of Honolulu on the island of Oahu. The city is the main gateway to Hawaii and a major portal into the United States. The city is also a major hub for international business, military defense, as well as famously being host to a diverse variety of east-west and Pacific culture, cuisine, and traditions. 

Honolulu is the most remote city of its size in the world and is the westernmost major U.S. city. For statistical purposes, the U.S. Census Bureau recognizes the approximate area commonly referred to as "City of Honolulu" (not to be confused with the "City and County") as a census county division (CCD). Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the city of Honolulu was 337,256 as of the 2010 census, while the Honolulu CCD was 390,738 and the population of the consolidated city and county was 953,207. 

"Honolulu" means "sheltered harbor" or "calm port". The old name is said to be Kou, a district roughly encompassing the area from Nuuanu Avenue to Alakea Street and from Hotel Street to Queen Street which is the heart of the present downtown district. The city has been the capital of the Hawaiian Islands since 1845 and gained historical recognition following the attack on Pearl Harbor by Japan near the city on December 7, 1941. question: What does Honolulu mean?

story: My dad runs the Blue Street Zoo. Everyone calls him the Zoo King. That means Mom is the Zoo Queen. And that means that I'm the Zoo Prince! Being a prince is very special. 

I spend every morning walking around to see the zoo. It's better than any animal book. I say hello to the lions. I say woof at all of the wolves. I make faces to the penguins. Once I even gave a morning kiss to a bear! My favorite animal is the piggy. I named him Samson. He likes to eat mustard, so I toss some mustard jars into his cage every morning. I don't know why that piggy likes mustard so much. 

Sometimes I walk around with the Zoo King and Zoo Queen. Then we say hello to the animals together! I really like those days. Everybody who works at the Zoo says hello to us when we walk by. At lunchtime, we all go to the Zoo restaurant and eat pork chops. I hope Samson doesn't get mad about that!, question: Where did they eat lunch?
Answer:
the Zoo restaurant
