Can you help me find a restaurant by the name of Bangkok City?
Certainly, bangkok city is a thai restaurant in the centre area in the expensive price range. Would you like their address?
No thank you. I would like to book a reservation for Wednesday at 5:45 pm.
and how many people will the reservation be for?
There are 6 of us.
Unfortunately, the restaurant is booked. Would you like to try another restaurant?
Yes. Something in the same area and same pricerange, please. 
I can book reservations for a thai in the centre area that meets your needs
Yes please that would be great. We love thai.
I am so sorry, but I was not able to book this.  Would you like to try a different restaurant?
Yes please try to book a different Thai restaurant.
Great news. I was able to book the Sala Thong and your reference number is VMHJ6Y3I.
Thanks so much. That is awesome! Have a good day!
You're very welcome. Goodbye.
