Hello, I am looking for a cheap restaurant that serves german food. 
It looks like there are no German restaurants in the city. Would you like me to check for a different type of restaurant?
Yes, how about portuguese food?
There are two restaurants in the cheap price range that serve Portuguese food. What area would you like to go to?
It doesn't matter.

I would like the address of Nandos restaurant, please.
Nandos is located in the south part of the city and the address is Cambridge Leisure Park Clifton Way.  Anything else you need?
Thank you, goodbye.
