Task-oriented dialogue about: restaurant

I am interested at eating at an expensive place in the west part of town.
We have nine expensive dining establishments on the west side. Cuisines offered are Thai, Indian, European, and British. Do you have a preference?
No I don't have a preference. I want to book for four people at 15:00 on Saturday.
Okay I booked a table for 4 at 15:00 on Saturday at the Graffiti, an expensive British restaurant in the west area of town.
Thank you. Can you please give me the reference number?

No that will be all. Thank you so much for all of your help!
Excellent. Have a good rest of your day!
