I'm thinking about going to Tokyo for a vacation. Know any good places to go there?
Oh there's a lot of things to do in Tokyo, the metropolitan prefecture!
Dang, I don't even know what that word means! What are some cool things to do? I really want to go eat sushi there.
You might try sashimi, too.  It's a related Japanese dish that has raw fish and optional serving of rice.
Ooooh, I love sashimi! What other Japanese dishes are popular in Tokyo?
Ceviche, which is raw fish cured in citrus juices is very popular!
Ceviche? I thought that was a Peruvian food! Sushi in citrus juice sounds great right now. 
It is Peruvian, but got influences from Europe and Asia.  Go vigure!
Do you know of any sweet sightseeing places in Tokyo?
I can't name any specific places, but it's been the capital since 1868 so there must be lots to do.
