Are there any expensive British restaurants in town?
There are 57 restaurants that match your specifications. Do you want anything more specific?
Yes, I'd like to find one in the west side of town.
I have two restaurants that meet your needs, Graffiti and Travellers Rest. Would you like to make a reservation at one of those? 
Yes, I need to book a table for five people at 17:15 for this Thursday.
I am unable to book a restaurant at that time on Thursday. Is there another day or time slot I can check for you?
Will you check 16:15?
A reservation at 16:15 was successful at Graffiti. Your reference number is VCCP7L4M. Is there anything else I can help you with today?
Thank you so much.   Have a nice day.  Bye.
You're welcome, have a good meal.
