Hi, I am looking for a restaurant in the south that serves Tuscan food.
I'm sorry, there are not Tuscan restaurants at all.  Can I find a different cuisine type for you?
Okay. That's fine. Can you find me one that serves chinese food? 
I have 3 chinese restaurants available.  Is there a price range you would prefer?
I don't care. I just need a table for 5 people at 12:45 on Tuesday if you can book me one.
I have the lucky star with is in the south and cheap.  Would you like me to book at that restaurant?
Lucky star. Sure why not.
Booking was unsuccessful. Would you like to try another time or different chinese restaurant?
Could you find me a place with the same price range in the same area?
The only other cheap restaurant in the center of the city is a Portuguese restaurant. Would you like me to book that for you.
Yes, please. Same people, date, and time.
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?
No I do not need anything else, thank you goodbye.
You're welcome, have a lovely day!
