U: Hi, I am looking for a restaurant in the south that serves Tuscan food.

S: I'm sorry, there are not Tuscan restaurants at all.  Can I find a different cuisine type for you?

U: Okay. That's fine. Can you find me one that serves chinese food?

S: I have 3 chinese restaurants available.  Is there a price range you would prefer?

U: I don't care. I just need a table for 5 people at 12:45 on Tuesday if you can book me one.

S: I have the lucky star with is in the south and cheap.  Would you like me to book at that restaurant?

U: Lucky star. Sure why not.

S: Booking was unsuccessful. Would you like to try another time or different chinese restaurant?

U: Could you find me a place with the same price range in the same area?

S: The only other cheap restaurant in the center of the city is a Portuguese restaurant. Would you like me to book that for you.

U: Yes, please. Same people, date, and time.

S: I was able to book at table at Nandos for the time and date specified. Your reference number is 0W15TQOH. Can I help you with anything else today?

U: Is the staff there known for friendly and responsive service?
S: While the food at the Nandos restaurant may be appealing, their service staff is found to be slow and with a negative attitude.
