I am looking for a restaurant in the centre that serves african food. 
The bedouin serves african food at 100 Mill Road City Centre. Would you like to make a booking?
I would like a restaurant in the expensive price range please. 
Bedouin is expensive. Would you like to book there?
Yes. I want to book a table for 3 people on Tuesday at 19:45.
That time slot is unavailable. Is there another time slot you want to book?
Could you try 18:45 instead?
Your table has been reserved at for 3 at 18:45 on Tuesday. The reference number is  IE3WWFDN.
Thank you very much. Have a great day.
You're quite welcome. Thanks for contacting the Cambridge TownInfo Centre and have a great day!
