Task-oriented dialogue about: restaurant

I'm looking for a moderately priced restaurant to eat at in the north.
I've found a Chinese restaurant and an Indian restaurant. Which one do you prefer?
Chinese would be great!
If you tell me a day and a time you would like to reserve, I can book that for you.
I would like a table for 8 people at 17:30 on Wednesday
Then booking was unsuccessful. Would you like me to try the Indian restaurant?
Okay, that sounds good. I'll need a reference number.
It's booked, your reference number is 5YBVERXA .
Thank you so much for your help.
No problem. I hope you have a great day. Good-Bye!
