Are there any expensive restaurants in the city centre you could recommend?
There are many expensive restaurants in the city centre. Do you have a cuisine preference? 
I would like to eat Indian food.
There are 5 Indian restaurants available in the centre. What day are you looking to dine?
I need a reservation for Thursday.  There will be 1 person at 11:15.  Any of the 5 restaurants would be fine.
I was able to get you a table at The Golden Curry. Your reference number is 7DD4DK3N and they'll hold your table for 15 minutes. Can I help with anything else?
Thank you and goodbye.
You're welcome. Goodbye.
